In this manual we provide an in-depth understanding of what goes into an Agent Model, how you can use the Agent Modeling Framework and related tools to design one and present tutorials to get you started. But before going into details, let's take a quick overview at what agent-based modeling is is and how the Agent Modeling Framework can help you to develop models for ABM or other problem domains.
We hope you enjoy using the tool, and we look forward to your comments and feedback and most of all participation!

==Agent-Based Modeling==
The primary focus of the Agent Modeling Platform tools is "Agent-Based Modeling" (ABM). ABM is an innovative technique used to explore complex phenomenon in many domains, including economics, social sciences, biomedicine, ecology and business operations. ABMs share characteristics with object models, but are:

Agent-Based Models (ABMs) seek to represent important real-world dynamics by designing communities of software agents that mimic real entities. Rather than make simplifying assumptions about such systems and then representing them in equation form or as off the shelf algorithmic constructs, the ABM researcher aims to identify key agent state, interaction spaces, and behaviors. Agents are then "let loose" on our computers and we explore what happens next. The computational horsepower exists today to simulate large numbers (e.g. >>10) of interacting, adaptive and autonomous agents but often desktop computers are all we need to explore significant domains. ABMs have been designed to represent all kinds of important natural systems, at scales reaching from cellular mechanics to international trade and are being used to solve truly hard problems in government, business, and academia. ABMs are not a solution to every problem, but they can help us to appreciate and gain unique insight into many systems, and often they can help us to come up with better practical decisions than we might using classic approaches.
-==Other Uses==
+==Other Domains==
Many kinds of objects share characteristics of ABM agents -- after all, software agents are used in many other contexts. The Agent Modeling Framework meta-modeling support is potentially suitable (or extendible) for a number of approaches outside of ABM; for example business rules, object interactions, systems dynamics models and traditional discrete event models. Similarly, AMP execution and graphic support can be used for modeling natural systems but could also be used to manage other software agents -- for example independent reasoning tasks or dynamic visualization support.

Escape is an exemplar ABM toolset. It's based on Ascape, which has been in use for more than 10 years. The core API is very stable, and that should give users a way to explore the features of AMP without concerns about keeping in synch with the rapidly evolving AXF /AGF API. It allows modelers to code in Java and/or generate models with AMF and then execute those models within the same development environment. Escape is the primary target for most of the models in this guide. Those users interested in writing code directly to the Escape API can refer to the Programmer Guide.

A primary purpose of the Escape project -- apart from the obvious goal of providing a nice Eclipse hosted ABM toolkit -- is to provide an exemplar to demonstrate how any arbitrary agent modeling framework can be integrated within the AMP environment. A cool aspect of this is that AMP has no dependencies on Escape, but also that the underlying ABM modeling framework for Escape has no dependencies on AMP -- instead Escape simply provides the runtime glue between AMP and the ABM framework. The underlying ABM framework uses the Ascape API, an API that first began development more than ten years ago and that has not been modified at all in order for it to work within the AMP environment.

-Because it's API is based on Ascape, Escape is one component of AMP that already has extensive documentation. There is complete Javadoc as well as a manual and other web resources. See the [http://ascape.sourceforge.net Ascape Website] to locate these resources. There is a [http://ascape.sourceforge.net/docs/TheAscapeManual5.pdf full manual] for Ascape available on that site.

+Many models have been created using Ascape over the years, including all of the classic models created at Brookings and some other cool models such as Craig Reynold's Boids and a pretty cool little traffic model, and they've all been converted to run in Escape. They're in Java but you can execute and explore them in exactly the same way as the Epidemic model above. All of the Ascape example models have been converted (a straightforward process) from their intial Ascape incarnations. For licensing reasons (they're BSD, not EPL) we can't host them directly on the Eclipse site. You can get the projects in two ways:

We need to put together a catalog here. Another nice opportunity for user contributions.)

There are a number of models developed with AMF that can automatically generate example models to run in Escape. There are two ways to run the example models:

We may simply package an Eclipse runtime convenience plugin to gather these dependencies up a bit.

+==Integrating Java and AMF Models==
If you're like many Java developers, you might find point-and-click interfaces a bit lame. Personally, I've changed my tune in this, and I now define all of my ABM models from the editor, saving Java for truly specialized tasks. But even without generation of agent behavior, Acore can be a really valuable tool, as the GIS example shows. The way to look at metaABM is as a way to compose your overall model and automate the tedious parts. Apart from Java generated code, the AMF meta-model maintains a number of very useful artifacts. For example, the Repast Simphony target maintains model.score and all of the model.rs component. Generally, AMF should save time and hassle while making your models far more transparent even if you never use the Actions component to define agent behavior.
-====Method Action====
+===Method Action===
As explained in the action section, you can simply create a "Method" act with hand-written Java code. This option is nice because all code is contained within the AMF file. But it can be difficult to maintain large blocks of Java code as you aren't using a Java editor to edit the Java code itself. One way to get around this is to create your code in the generated Java method and then copy it into the Method action. Note one imporant issue here -- you'll generally have to fully qualify your Java references as you won't be able to change the imports statements directly.
-====Protected Code Regions====
+===Protected Code Regions===
You can mix and match Action behavior with Java and generated code with POJOs. One way to do this is through using protected regions. Select the agent you want to create protected methods for and then select "Generate Protected" from the "Mode" property. Now, create actions just as you have before, or use your existing ones. On code generation, open up the relevant java file and examine the methods that have been created.

====Configuration====
Instead of using Ant, Escape has really nice support for parameterizing and testing models. See [[Experimenting and Testing]] (todo). If you do want to work with ant you will need to install the plugins from the Sourceforge download site. (These have dependencies that I didn't want to bother with going through the Eclipse IP process to get in. If for some reason you think these should be part of core Escape let Miles know and I'll take care of it.) Ant has not been tested for Escape so it's not even clear it will work.
-==Running Agent Models==
+=Installation Guide=
+==Tools==
-===Exploring Example ABM Models===
+===Complete IDE===
-The first thing most people will want to do in AMP is to play with the example models. You can explore AMF models as well as some really interesting classic ABM models.
+You may already have obtained a complete IDE bundled with AMP and other modeling tools. The project contributors offer open source and commercial versions of the AMP tools, which you can find at their sites. If so, you can mostly ignore this chapter unless you want to install an optional component like Repast.
-====Downloading Models====
+===Eclipse and the Agent Modeling Tools===
-To obtain the models, simply launch the cheat sheet. Go to the '''Help > Cheat Sheets...''' menu and choose "Load Sample Projects".
+You can find more detailed instructions [http://eclipse.org/amp/installing/ here], but here are the basic steps.
-Or you can get them yourself from the following locations:
+#Install the latest version of Eclipse from [http://www.eclipse.org/downloads/ here]. AMP requires version 3.5.x (Gallieo) or higher. Version 3.6 (Hellos) which is currently a development (beta) release works well too. We recommend the "Classic" release at the bottom of the page as the other releases have a bunch of stuff you wont' need.
+#Add update sites for AMP and AMP dependencies. See the screenshot below and the [http://help.eclipse.org/galileo/topic/org.eclipse.platform.doc.user/tasks/tasks-124.htm Eclipse Documentation]. There are different versions of the update sites, depending on whether you want to use the most stable version of the toolset or the "latest and greatest". The update sites are listed below.
+#(Optional) If you install and AMP extensions, add Update Sites for them -- they're also listed below.
+#Select the features that you want to install.
+#Click the '''Next''' button, review the licenses, and then click '''Finish'''.
-=====AMF Models=====
+Agent Modeling Platform update sites:
+ Milestones (recommended): http://download.eclipse.org/amp/updates/milestones
+ Interim (newer): http://download.eclipse.org/amp/updates/interim
+ Nightly (bleeding edge): http://download.eclipse.org/amp/updates/nightly
- org.eclipse.amp/org.eclipse.amp.amf/examples/org.eclipse.amp.amf.examples.escape
+Update sites for AMP Extensions
+ AGF 3D (recommended): http://lwjgl.org/update
+ AMF for Ascape (recommended for Java developers): http://ascape.sourceforge.net/eclipse
+ AMF for Repast (for people using Repast): http://mirror.anl.gov/pub/repastsimphony/site.xml (non P2)
-To understand the capabilities of AMF, you might also want to try out running the same models automatically generated for Ascape or Repast. These are located at dev.eclipse.org in cvsroot/modeling:
+In the following screenshot, we've added the LWJGL site (not shown) as well as the Ascape site (not shown), but not the Repast site, and we're about to install the respective features.

+[[Image:images/resources/AMPUpdateSite.png]]
-=====Escape / Ascape Java Models=====
+Once you've done that, select the '''Help > Help Contents''' menu, find the Agent Modeling Guide and open this overview page within that guide.
-These are SVN projects in the sourceforge SVN. For help, see [[http://www.eclipse.org/subversive/documentation/teamSupport/find_check_wiz.php this page]].

+====Ascape====
+
+For licensing and copyright reasons we can't provide all of the Ascape tools and manual on the Eclipse hosted Agent Modeling Project site. None of these tools are necessary to use AMP (the core Ascape support is an IP approved part of the AMP distribution) but they're highly recommended. The Ascape tools include:
+
+#An excellent Manual covering programming Java models in Ascape and Escape. (The API is the same.)
+#Support for creating Ascape Java projects and executing the Swing-based Java Applications. Swing deployed Ascape Java Applications can be as small as 10MB and can be deployed to the web.
+#Eclipse based IDE support for plain Java Ascape projects.
+
+The Ascape update site is at:
+
+ http://ascape.sourceforge.net/eclipse
-====Generating Models====
+To install Ascape, use the update manager. Select '''Help > Install New Software..."''', add the Ascape update site, select the Ascape category and click the '''Finish''' button.
-There are a number of models developed with AMF that can automatically generate example models to run in Escape. There are two ways to run the example models:
+[[Image:images/resources/AscapeUpdateSite.png]]
-=====Creating a New Escape Project=====
+====Repast====
-The best option is to simply create a new Escape project and drag the models into it!
+The Repast update site is at:
-#If you're not already there, open the Agent Modeling Perspective. Select Window > Open Perspective > Other.. and then Agent Modeling. (Or you can choose Window > Reset Perspective and the Agent Modeling perspective should appear in the Open Perspective list itself.)
-#Next, let's create the project where we'll place our model. Select File > New > Escape AMF Project. Give it a name like "escape.tutorial", then click Finish.
-#Finally grab the Epidemic.metaabm model at http://download.eclipse.org/amp/models/Epidemic.metaabm and drag it into the project. (Depending on your browser the file may load as text directly into your browser, in which case just right-click on the link and save it to a file.)
+ http://mirror.anl.gov/pub/repastsimphony/site.xml
-===Tutorial===
+More information on downloading and installing repast can be found [http://repast.sourceforge.net/docs/development.html here]. Follow the instrucitons for "Configuration B".
-We've developer have a complete cheat sheet supporting this tutorial. Simply go to '''Help > Cheat Sheets...''' and then select "Run an Example Model" from within the "Agent Modeling" category.

-
-===Classic Java ABM Models===
-
-Many models have been created using Ascape over the years, including all of the classic models created at Brookings and some other cool models such as Craig Reynold's Boids and a pretty cool little traffic model, and they've all been converted to run in Escape. They're in Java but you can execute and explore them in exactly the same way as the Epidemic model above. All of the Ascape example models have been converted (a straightforward process) from their intial Ascape incarnations. For licensing reasons (they're BSD, not EPL) we can't host them directly on the Eclipse site. You can get the projects in two ways:
-
-Once you've downloaded the projects, open up the src folder and navigate to the Java files for the actual models. For example, to run Conway's Life, you'll want src/edu.brook.life.ConwayLife. Right-click on the Java file and select "Execute". There are many models to explore! (It's not always obvious which Java files are for models, so you may have to poke around a bit. We need to put together a catalog here. Another nice opportunity for user contributions.)

<para>Existing scientific models are very good at representing relatively simple systems, but generally speaking aren't very good at representing complex systems.

<para>Agent-Based Models (ABMs) seek to represent important real-world dynamics by designing communities of software agents that mimic real entities. Rather than make simplifying assumptions about such systems and then representing them in equation form or as off the shelf algorithmic constructs, the ABM researcher aims to identify key agent state, interaction spaces, and behaviors. Agents are then "let loose" on our computers and we explore what happens next. The computational horsepower exists today to simulate large numbers (e.g. >>10) of interacting, adaptive and autonomous agents but often desktop computers are all we need to explore significant domains. ABMs have been designed to represent all kinds of important natural systems, at scales reaching from cellular mechanics to international trade and are being used to solve truly hard problems in government, business, and academia. ABMs are not a solution to every problem, but they can help us to appreciate and gain unique insight into many systems, and often they can help us to come up with better practical decisions than we might using classic approaches.</para>

<para>A primary purpose of the Escape project -- apart from the obvious goal of providing a nice Eclipse hosted ABM toolkit -- is to provide an exemplar to demonstrate how any arbitrary agent modeling framework can be integrated within the AMP environment. A cool aspect of this is that AMP has no dependencies on Escape, but also that the underlying ABM modeling framework for Escape has no dependencies on AMP -- instead Escape simply provides the runtime glue between AMP and the ABM framework. The underlying ABM framework uses the Ascape API, an API that first began development more than ten years ago and that has not been modified at all in order for it to work within the AMP environment.</para>

Personally, I've changed my tune in this, and I now define all of my ABM models from the editor, saving Java for truly specialized tasks. But even without generation of agent behavior, Acore can be a really valuable tool, as the GIS example shows. The way to look at metaABM is as a way to compose your overall model and automate the tedious parts. Apart from Java generated code, the AMF meta-model maintains a number of very useful artifacts. For example, the Repast Simphony target maintains model.score and all of the model.rs component.

One way to get around this is to create your code in the generated Java method and then copy it into the Method action.

- <title>Convert the low-level imports from AWT and Swing to SWT</title>
- <para>The simplest way to accomplish this is to remove all of the imports and then organize imports. For example:</para>
- <literallayout>java.awt.Color => org.eclipse.swt.graphics.Color
-java.awt.Graphics => org.eclipse.draw2d.Graphics
-</literallayout>
- <para>Then just do a global find for all of the imports and replace them with nothing. This is a great place for a regexp. Try:</para>
- <literallayout>find: import java\.awt\.(.*);
-replace: [nothing]
-</literallayout>
- <para>You don't have to replace these with the SWT equivalents, just click on the project, right-click and choose "Source:Organize Imports.."
- By the way, a great way to avoid having to select the right entries in optimize imports and to alert you when you have missed anything is to prevent the awt and swing classes from being used at all. Right-click on project, choose "Build Path:Configure Build Path", go to Libraries tab, open JRE System Library, choose "Access Rules", edit, and then add entries for java/awt/** and javax/swing/**. The code will regenerate and you'll have error markers for all of the stuff that won't work with Escape and Eclipse.</para>

-new Color(Math.min(1.0f, (float) (redEnergy + orangeEnergy)), (float) orangeEnergy * .8f, (float) blueEnergy) =>

+ <title>Convert the low-level imports from AWT and Swing to SWT</title>
+ <para>The simplest way to accomplish this is to remove all of the imports and then organize imports. For example:</para>
+ <literallayout>java.awt.Color => org.eclipse.swt.graphics.Color
+java.awt.Graphics => org.eclipse.draw2d.Graphics
+</literallayout>
+ <para>Then just do a global find for all of the imports and replace them with nothing. This is a great place for a regexp. Try:</para>
+ <literallayout>find: import java\.awt\.(.*);
+replace: [nothing]
+</literallayout>
+ <para>You don't have to replace these with the SWT equivalents, just click on the project, right-click and choose "Source:Organize Imports.."
+ By the way, a great way to avoid having to select the right entries in optimize imports and to alert you when you have missed anything is to prevent the awt and swing classes from being used at all. Right-click on project, choose "Build Path:Configure Build Path", go to Libraries tab, open JRE System Library, choose "Access Rules", edit, and then add entries for java/awt/** and javax/swing/**. The code will regenerate and you'll have error markers for all of the stuff that won't work with Escape and Eclipse.</para>

+ <title>Convert color features</title>
+ <para>You can't use AWT colors either so you'll need to replace any colors. AMP provides a convenience classes for Colors called ColorFeature and ColorFeatureConcrete. You can use these or any of the other ways to define SWT colors. For example:</para>

+new Color(Math.min(1.0f, (float) (redEnergy + orangeEnergy)), (float) orangeEnergy * .8f, (float) blueEnergy) =>

<para>Existing scientific models are very good at representing relatively simple systems, but generally speaking aren't very good at representing complex systems.

<para>Agent-Based Models (ABMs) seek to represent important real-world dynamics by designing communities of software agents that mimic real entities. Rather than make simplifying assumptions about such systems and then representing them in equation form or as off the shelf algorithmic constructs, the ABM researcher aims to identify key agent state, interaction spaces, and behaviors. Agents are then "let loose" on our computers and we explore what happens next. The computational horsepower exists today to simulate large numbers (e.g. >>10) of interacting, adaptive and autonomous agents but often desktop computers are all we need to explore significant domains. ABMs have been designed to represent all kinds of important natural systems, at scales reaching from cellular mechanics to international trade and are being used to solve truly hard problems in government, business, and academia. ABMs are not a solution to every problem, but they can help us to appreciate and gain unique insight into many systems, and often they can help us to come up with better practical decisions than we might using classic approaches.</para>

It allows modelers to code in Java and/or generate models with AMF and then execute those models within the same development environment. Escape is the primary target for most of the models in this guide. Those users interested in writing code directly to the Escape API can refer to the Programmer Guide.</para>

<para>A primary purpose of the Escape project -- apart from the obvious goal of providing a nice Eclipse hosted ABM toolkit -- is to provide an exemplar to demonstrate how any arbitrary agent modeling framework can be integrated within the AMP environment. A cool aspect of this is that AMP has no dependencies on Escape, but also that the underlying ABM modeling framework for Escape has no dependencies on AMP -- instead Escape simply provides the runtime glue between AMP and the ABM framework. The underlying ABM framework uses the Ascape API, an API that first began development more than ten years ago and that has not been modified at all in order for it to work within the AMP environment.</para>

- <para>If you're like many Java developers, you might find point-and-click interfaces a bit lame. Personally, I've changed my tune in this, and I now define all of my ABM models from the editor, saving Java for truly specialized tasks. But even without generation of agent behavior, Acore can be a really valuable tool, as the GIS example shows. The way to look at metaABM is as a way to compose your overall model and automate the tedious parts. Apart from Java generated code, the AMF meta-model maintains a number of very useful artifacts. For example, the Repast Simphony target maintains model.score and all of the model.rs component. Generally, AMF should save time and hassle while making your models far more transparent even if you never use the Actions component to define agent behavior.</para>

- <title>Method Action</title>
- <para>As explained in the action section, you can simply create a "Method" act with hand-written Java code. This option is nice because all code is contained within the AMF file. But it can be difficult to maintain large blocks of Java code as you aren't using a Java editor to edit the Java code itself. One way to get around this is to create your code in the generated Java method and then copy it into the Method action. Note one imporant issue here -- you'll generally have to fully qualify your Java references as you won't be able to change the imports statements directly. </para>

- <title>Convert the low-level imports from AWT and Swing to SWT</title>
- <para>The simplest way to accomplish this is to remove all of the imports and then organize imports. For example:</para>
- <literallayout format="linespecific" class="normal">java.awt.Color => org.eclipse.swt.graphics.Color
-java.awt.Graphics => org.eclipse.draw2d.Graphics
-</literallayout>
- <para>Then just do a global find for all of the imports and replace them with nothing. This is a great place for a regexp. Try:</para>
- <literallayout format="linespecific" class="normal">find: import java\.awt\.(.*);
-replace: [nothing]
-</literallayout>
- <para>You don't have to replace these with the SWT equivalents, just click on the project, right-click and choose "Source:Organize Imports.."
- By the way, a great way to avoid having to select the right entries in optimize imports and to alert you when you have missed anything is to prevent the awt and swing classes from being used at all. Right-click on project, choose "Build Path:Configure Build Path", go to Libraries tab, open JRE System Library, choose "Access Rules", edit, and then add entries for java/awt/** and javax/swing/**. The code will regenerate and you'll have error markers for all of the stuff that won't work with Escape and Eclipse.</para>

+ <title>Integrating Java and AMF Models</title>
+ <para>If you're like many Java developers, you might find point-and-click interfaces a bit lame. Personally, I've changed my tune in this, and I now define all of my ABM models from the editor, saving Java for truly specialized tasks. But even without generation of agent behavior, Acore can be a really valuable tool, as the GIS example shows. The way to look at metaABM is as a way to compose your overall model and automate the tedious parts. Apart from Java generated code, the AMF meta-model maintains a number of very useful artifacts. For example, the Repast Simphony target maintains model.score and all of the model.rs component. Generally, AMF should save time and hassle while making your models far more transparent even if you never use the Actions component to define agent behavior.</para>
+ <section id="Method_Action">
+ <title>Method Action</title>
+ <para>As explained in the action section, you can simply create a "Method" act with hand-written Java code. This option is nice because all code is contained within the AMF file. But it can be difficult to maintain large blocks of Java code as you aren't using a Java editor to edit the Java code itself. One way to get around this is to create your code in the generated Java method and then copy it into the Method action. Note one imporant issue here -- you'll generally have to fully qualify your Java references as you won't be able to change the imports statements directly. </para>
+ </section>
+ <section id="Protected_Code_Regions">
+ <title>Protected Code Regions</title>
+ <para>You can mix and match Action behavior with Java and generated code with POJOs. One way to do this is through using protected regions. Select the agent you want to create protected methods for and then select "Generate Protected" from the "Mode" property. Now, create actions just as you have before, or use your existing ones. On code generation, open up the relevant java file and examine the methods that have been created. </para>

+ <para>Because Escape uses SWT and Ascape uses Swing, there are a few unavoidable incompatibilities. Most of these we avoid by using higher level APIs but here are the key changes that you're likely to have to make:</para>
+ <section id="Convert_the_low-level_imports_from_AWT_and_Swing_to_SWT">
+ <title>Convert the low-level imports from AWT and Swing to SWT</title>
+ <para>The simplest way to accomplish this is to remove all of the imports and then organize imports. For example:</para>
+ <literallayout format="linespecific" class="normal">java.awt.Color => org.eclipse.swt.graphics.Color
+java.awt.Graphics => org.eclipse.draw2d.Graphics
+</literallayout>
+ <para>Then just do a global find for all of the imports and replace them with nothing. This is a great place for a regexp. Try:</para>
+ <literallayout format="linespecific" class="normal">find: import java\.awt\.(.*);
+replace: [nothing]
+</literallayout>
+ <para>You don't have to replace these with the SWT equivalents, just click on the project, right-click and choose "Source:Organize Imports.."
+ By the way, a great way to avoid having to select the right entries in optimize imports and to alert you when you have missed anything is to prevent the awt and swing classes from being used at all. Right-click on project, choose "Build Path:Configure Build Path", go to Libraries tab, open JRE System Library, choose "Access Rules", edit, and then add entries for java/awt/** and javax/swing/**. The code will regenerate and you'll have error markers for all of the stuff that won't work with Escape and Eclipse.</para>
+ </section>
+ <section id="Convert_color_features">
+ <title>Convert color features</title>
+ <para>You can't use AWT colors either so you'll need to replace any colors. AMP provides a convenience classes for Colors called ColorFeature and ColorFeatureConcrete. You can use these or any of the other ways to define SWT colors. For example:</para>
+ <literallayout format="linespecific" class="normal">Color.lightGray => ColorFeature.LIGHT_GRAY
+new Color(Math.min(1.0f, (float) (redEnergy + orangeEnergy)), (float) orangeEnergy * .8f, (float) blueEnergy) =>

+ <section id="Modify_usages_of_DrawFeatures">
+ <title>Modify usages of DrawFeatures</title>
+ <para>If you've created any of your own draw features, you'll need to change them slightly to accommodate the differences between the AWT and SWT / Draw2D APIs. This should be pretty straightforwrd. For example:</para>
+ <literallayout format="linespecific" class="normal">g.setColor(...
+g.fillOval(..

+g.setBackgroundColor(

Agent-Based Models (ABMs) seek to represent important real-world dynamics by designing communities of software agents that mimic real entities. Rather than make simplifying assumptions about such systems and then representing them in equation form or as off the shelf algorithmic constructs, the ABM researcher aims to identify key agent state, interaction spaces, and behaviors. Agents are then "let loose" on our computers and we explore what happens next. The computational horsepower exists today to simulate large numbers (e.g. >>10) of interacting, adaptive and autonomous agents but often desktop computers are all we need to explore significant domains. ABMs have been designed to represent all kinds of important natural systems, at scales reaching from cellular mechanics to international trade and are being used to solve truly hard problems in government, business, and academia. ABMs are not a solution to every problem, but they can help us to appreciate and gain unique insight into many systems, and often they can help us to come up with better practical decisions than we might using classic approaches.
-==Other Uses==
+==Other Domains==
Many kinds of objects share characteristics of ABM agents -- after all, software agents are used in many other contexts. The Agent Modeling Framework meta-modeling support is potentially suitable (or extendible) for a number of approaches outside of ABM; for example business rules, object interactions, systems dynamics models and traditional discrete event models. Similarly, AMP execution and graphic support can be used for modeling natural systems but could also be used to manage other software agents -- for example independent reasoning tasks or dynamic visualization support.
+
+==The Agent Modeling Platform (AMP)==
+
+The Eclipse Agent Modeling Project (Incubation) or "AMP" provides the core support for both open source and commercial modeling tools. AMP in turn is built upon Elipse, the most powerful, well-supported and popular Integrated Development Platform (IDE) available anywhere.
+
+AMP provides extensible frameworks and exemplary tools for representing, editing, generating, executing and visualizing ABMs and any other domain requiring spatial, behavioral and functional features. AMP has two main themes that complement but don't depend on one another, modeling of agent systems (AMF) and execution and exploration of those systems (AXF, AGF and Escape).
+
+The overall AMP architecture and project dependencies are summarized in the architectural diagram below:
+
+[[Image:images/AMPArchitectureDiagram.jpg]]
+
+===Agent Modeling Framework (AMF)===
+
+AMF provides an ABM meta-model representation, editor, generator and development environment. The AMF Acore meta-model is similar to EMF Ecore and defined in Ecore, but provides high-level support for complex agents.AMF generates complete executable models for Escape, Ascape and Repast Simphony, as well as Java Skeletons and Interfaces, JUnit test cases and documentation and is easily extensible to support additional targets. For more on AMF, see the Modeler Guide.
+
+===Agent Execution Framework (AXF)===
+The execution framework provides services and UI for model management, execution, and views. Arbitrary toolkits can easily integrate with Eclipse and AXF by implementing pluggable providers like engines, agents and view parts. AXF is not just for ABM -- anyone who needs support for executing, managing and visualizing collections of objects may find it useful. AXF user tools are covered extensively in the User Guide, and the forthcoming Platform Developers Guide will provide information about integrating AXF in your own tools.
+
+===Agent Graphics Framework (AGF)===
+
+The graphics framework extends GEF, GEF3D, Zest, and the BIRT charting engine to support real-time visualization of and interaction with agent models. AGF currently provides support for 2D, 2 1/2 D. and graph structures, and will be extended to 3-D, GIS and others. As with other AMP components, the AGF design focus is to provide an extensible infrastructure so that platform adopters can easily create their own view and editor parts. AGF user tools are covered extensively in the User Guide, and the forthcoming Platform Developers Guide will provide information about integrating and extending AGF in your own tools.
+
+===Escape===
+
+Escape is an exemplar ABM toolset. It's based on Ascape, which has been in use for more than 10 years. The core API is very stable, and that should give users a way to explore the features of AMP without concerns about keeping in synch with the rapidly evolving AXF /AGF API. It allows modelers to code in Java and/or generate models with AMF and then execute those models within the same development environment. Escape is the primary target for most of the models in this guide. Those users interested in writing code directly to the Escape API can refer to the Programmer Guide.

A primary purpose of the Escape project -- apart from the obvious goal of providing a nice Eclipse hosted ABM toolkit -- is to provide an exemplar to demonstrate how any arbitrary agent modeling framework can be integrated within the AMP environment. A cool aspect of this is that AMP has no dependencies on Escape, but also that the underlying ABM modeling framework for Escape has no dependencies on AMP -- instead Escape simply provides the runtime glue between AMP and the ABM framework. The underlying ABM framework uses the Ascape API, an API that first began development more than ten years ago and that has not been modified at all in order for it to work within the AMP environment.
-==Getting Started==
+==Documentation==
-===Documentation and other Resources===
+In addition to this documentation, there are a number of other resources available related to Escape development. Because it's API is based on Ascape, a lot of resources developed for Ascape are equally applicable to Ascape. The Ascape documentation is bundled with some distributions of the AMP tools, but if you are using the Eclipse AMP download, you can access it online or install it from the Ascape update site.
-Because it's API is based on Ascape, Escape is one component of AMP that already has extensive documentation. There is complete Javadoc as well as a manual and other web resources. See the [http://ascape.sourceforge.net Ascape Website] to locate these resources. There is a [http://ascape.sourceforge.net/docs/TheAscapeManual5.pdf full manual] for Ascape available on that site. Or, you can install the Ascape Manual into the eclipse help system by adding the following update site and selecting the "Documentations and Source Code" feature.

-===Installation===
+===Update Site===
-Escape is [http://eclipse.org/amp/installing/ installed] by default with the other model components. If you want to do 3D (really 2 1/2) visualizations, you will want AGF3D and the LWJGL dependency. You can build from source but in that case you'l need to launch a self-hosted runtime, so it's best to simply install from the update site if you're not actually doing AMP development.

+
+===Exploring Example ABM Models===
+
+The first thing most people will want to do in AMP is to play with the example models. You can explore AMF models as well as some really interesting classic ABM models.
+
+====Installing Models====
+
+See the Installation Guide to find out how to get the example models.
+
+=====AMF Models=====
+
+All AMF models produce pure Java code so they can be used like any other Escape Java model.
+
+ org.eclipse.amp/org.eclipse.amp.amf/examples/org.eclipse.amp.amf.examples.escape
+
+To understand the capabilities of AMF in producing other kinds of Java models, you might also want to try out running the same models automatically generated for Ascape or Repast. These are located at dev.eclipse.org in cvsroot/modeling:

+ org.eclipse.amp/org.eclipse.amp.amf/examples/org.eclipse.amp.amf.examples.repast
+
+=====Classic Escape / Ascape Java Models=====
+
+Many models have been created using Ascape over the years, including all of the classic models created at Brookings and some other cool models such as Craig Reynold's Boids and a pretty cool little traffic model, and they've all been converted to run in Escape. They're in Java but you can execute and explore them in exactly the same way as the Epidemic model above. All of the Ascape example models have been converted (a straightforward process) from their intial Ascape incarnations. For licensing reasons (they're BSD, not EPL) we can't host them directly on the Eclipse site. You can get the projects in two ways:
+
+Once you've downloaded the projects, open up the src folder and navigate to the Java files for the actual models. For example, to run Conway's Life, you'll want src/edu.brook.life.ConwayLife. Right-click on the Java file and select "Execute". There are many models to explore! (It's not always obvious which Java files are for models, so you may have to poke around a bit. We need to put together a catalog here. Another nice opportunity for user contributions.)
+
+These are SVN projects in the sourceforge SVN. For help, see [[http://www.eclipse.org/subversive/documentation/teamSupport/find_check_wiz.php this page]].

+ http://ascape.svn.sourceforge.net/svnroot/ascape/org.ascape.escape.models.examples
+
+====Generating Models====
+
+And of course, you can always use the AMF tools to generate models and then customize them from there. See the following section on integrating AMF with Java for more on that. There are a number of models developed with AMF that can automatically generate example models to run in Escape. There are two ways to run the example models:
+
+=====Creating a New Escape Project=====
+
+The best option is to simply create a new Escape project and drag the models into it!
+
+#If you're not already there, open the Agent Modeling Perspective. Select Window > Open Perspective > Other.. and then Agent Modeling. (Or you can choose Window > Reset Perspective and the Agent Modeling perspective should appear in the Open Perspective list itself.)
+#Create the project where we'll place our model. Select File > New > Escape AMF Project. Give it a name like "escape.tutorial", then click Finish.
+#Finally grab the Epidemic.metaabm model at http://download.eclipse.org/amp/models/Epidemic.metaabm and drag it into the project. (Depending on your browser the file may load as text directly into your browser, in which case just right-click on the link and save it to a file.)
==Developing Models==
The easiest way for Java developers to get started doing agent-based modeling in Eclipse is to begin to write programs using it. To develop new models, you can:
-# Create a new Escape project. The Escape projects are actually configured for AMF code generation so there are dependencies and builders in there that you don't need; you can remove all of the escape builders and any of the kitchen sink items. The "Create an Escape Java Model" cheat sheet will walk you through the process of creating a new Java based project and model.
-# Or for more experienced Eclipse users, you can simply to just create a new Plugin Project and add the necessary dependencies there. Have a look at the example escape project to see what you need. Note that you will likely need more dependencies then you need to simply build -- this is because the class loader uses the classes from the project path and so runtime classes have to be there as well. We may simply package an Eclipse runtime convenience plugin to gather these dependencies up a bit.
+===Cheatsheet===
-Then just create new Java classes for your root model scape and agents just as you would for an Ascape project.
+By far the simplest way to get started is with the cheatsheet. This walks you through the complete process of creating a Java based model. '''Help > Cheat Sheets...''' and then select "Create an Escape Java Model" from within the "Agent Modeling" category.

+==Integrating Java and AMF Models==
If you're like many Java developers, you might find point-and-click interfaces a bit lame. Personally, I've changed my tune in this, and I now define all of my ABM models from the editor, saving Java for truly specialized tasks. But even without generation of agent behavior, Acore can be a really valuable tool, as the GIS example shows. The way to look at metaABM is as a way to compose your overall model and automate the tedious parts. Apart from Java generated code, the AMF meta-model maintains a number of very useful artifacts. For example, the Repast Simphony target maintains model.score and all of the model.rs component. Generally, AMF should save time and hassle while making your models far more transparent even if you never use the Actions component to define agent behavior.
-====Method Action====
+===Method Action===
As explained in the action section, you can simply create a "Method" act with hand-written Java code. This option is nice because all code is contained within the AMF file. But it can be difficult to maintain large blocks of Java code as you aren't using a Java editor to edit the Java code itself. One way to get around this is to create your code in the generated Java method and then copy it into the Method action. Note one imporant issue here -- you'll generally have to fully qualify your Java references as you won't be able to change the imports statements directly.
-====Protected Code Regions====
+===Protected Code Regions===
You can mix and match Action behavior with Java and generated code with POJOs. One way to do this is through using protected regions. Select the agent you want to create protected methods for and then select "Generate Protected" from the "Mode" property. Now, create actions just as you have before, or use your existing ones. On code generation, open up the relevant java file and examine the methods that have been created.

Right-click on project, choose "Build Path:Configure Build Path", go to Libraries tab, open JRE System Library, choose "Access Rules", edit, and then add entries for java/awt/** and javax/swing/**.

new Color(Math.min(1.0f, (float) (redEnergy + orangeEnergy)), (float) orangeEnergy * .8f, (float) blueEnergy) =>

Version 3.6 (Hellos) which is currently a development (beta) release works well too. We recommend the "Classic" release at the bottom of the page as the other releases have a bunch of stuff you wont' need.
+#Add update sites for AMP and AMP dependencies. See the screenshot below and the [http://help.eclipse.org/galileo/topic/org.eclipse.platform.doc.user/tasks/tasks-124.htm Eclipse Documentation]. There are different versions of the update sites, depending on whether you want to use the most stable version of the toolset or the "latest and greatest". The update sites are listed below.

+Once you've done that, select the '''Help > Help Contents''' menu, find the Agent Modeling Guide and open this overview page within that guide.
+
+===Extensions===
+
+====Ascape====
+
+For licensing and copyright reasons we can't provide all of the Ascape tools and manual on the Eclipse hosted Agent Modeling Project site. None of these tools are necessary to use AMP (the core Ascape support is an IP approved part of the AMP distribution) but they're highly recommended. The Ascape tools include:
+
+#An excellent Manual covering programming Java models in Ascape and Escape. (The API is the same.)
+#Support for creating Ascape Java projects and executing the Swing-based Java Applications. Swing deployed Ascape Java Applications can be as small as 10MB and can be deployed to the web.
+#Eclipse based IDE support for plain Java Ascape projects.
+
+The Ascape update site is at:
+
+ http://ascape.sourceforge.net/eclipse
+
+To install Ascape, use the update manager. Select '''Help > Install New Software..."''', add the Ascape update site, select the Ascape category and click the '''Finish''' button.
+
+[[Image:images/resources/AscapeUpdateSite.png]]
+
+====Repast====

+The Repast update site is at:
+
+ http://mirror.anl.gov/pub/repastsimphony/site.xml
+
+More information on downloading and installing repast can be found [http://repast.sourceforge.net/docs/development.html here]. Follow the instrucitons for "Configuration B".

<td>Before getting into the details of how each Actions work together, or the various kinds of Actions, it will be helpful to take a broad overview of how they all fit together. As discussed above, actions are strung together in a sequence or flow. They're always composed of two parts, though those parts can be assembled and intermixed in many different ways. First, we search for a collection of agents, and then we do something with that selection. We refer to these two parts as Selections and Commands. (For the technically minded, another useful way of looking at the Actions approach is as a Query Transformation language, as with SQL and Stored Procedures. Except again, the results of the queries along with the transformations flow through from one query to the next.) Selections find the agents we want to do something with, and the commands do it. We need some way to start the whole chain of actions off, and so we have a kind of Selection called a Root Selection, or simply a Root. Secondly, we need some way to actually make the agents exist in the model in the first place, so we have a Create Agents action. Finally, we have special commands called builders that allow us to create the spaces that the agents will occupy. The various actions are discussed in depth in the Details section.</td>
@@ -94,7 +94,7 @@
An important aspect of the Actions design is that loop structures are not allowed -- that is, flows are acyclic. An action can never have an ancestor target (that is targets, targets of targets, etc..) that has as one of its ancestors that same action. As you'll see, actions don't typically
<span class="italic">need</span> loop structures. By far the most common use of loops in conventional programming langauges is to loop through collections of objects. As selections (see below) refer to the entire collection of agents, any actions on a selection apply to all members of that collection. Recursive structures are needed for some particular usages and will be supported in future releases, but not through an explicit looping construct.

<p>Selections are a key concept in Actions. Put simply, selections define what we are searching for and where. They are defined by a combination of Select, Query and Logic Actions.

Queries can be used to further refine selections either immediately after or later in the Action flow, as described in the next section. Logic Actions are used to combine and organize the Action flow defined by Query Actions.

Consider the example to the right. As we'll see in the detailed explanation of each Action below, Transformation Actions such as Move or Connect take multiple selections. The first selection defines the set of agents that will be performing the action. In the case of a Move agent, this refers to the mover. The second selection, which for Move we call "destination", refers to the selection that will be receiving the action. In the case of movement this is the agent or location that the Rule agent will be moving to.

The world is full of complex systems, and our misunderstanding of these systems has prevented us from addressing many of the key challenges facing the world, including the global financial crisis and climate change -- in fact once could argue that our misunderstanding of these systems has strongly contributed to these crises.</p>
+<p>Agent-Based Models (ABMs) seek to represent important real-world dynamics by designing communities of software agents that mimic real entities. Rather than make simplifying assumptions about such systems and then representing them in equation form or as off the shelf algorithmic constructs, the ABM researcher aims to identify key agent state, interaction spaces, and behaviors. Agents are then "let loose" on our computers and we explore what happens next. The computational horsepower exists today to simulate large numbers (e.g. >>10) of interacting, adaptive and autonomous agents but often desktop computers are all we need to explore significant domains. ABMs have been designed to represent all kinds of important natural systems, at scales reaching from cellular mechanics to international trade and are being used to solve truly hard problems in government, business, and academia. ABMs are not a solution to every problem, but they can help us to appreciate and gain unique insight into many systems, and often they can help us to come up with better practical decisions than we might using classic approaches.</p>

+<p>There are only a few changes should have to make to existing Ascape models or to use existing Ascape documentation to develop Escape models.</p>
+<div class="section" title="Model">
+<div class="titlepage">
+<div>
+<div>
+<h3 class="title">
+<a name="Model"></a>Model</h3>
+</div>

+<p>The core model is completely API compatible. No changes!</p>

+</div>
+</div>
+</div>
+<p>Because Escape uses SWT and Ascape uses Swing, there are a few unavoidable incompatibilities. Most of these we avoid by using higher level APIs but here are the key changes that you're likely to have to make:</p>
+<div class="section" title="Convert the low-level imports from AWT and Swing to SWT">
+<div class="titlepage">
+<div>
+<div>
+<h4 class="title">
+<a name="Convert_the_low-level_imports_from_AWT_and_Swing_to_SWT"></a>Convert the low-level imports from AWT and Swing to SWT</h4>
+</div>
+</div>
+</div>
+<p>The simplest way to accomplish this is to remove all of the imports and then organize imports. For example:</p>
+<div class="literallayout">
+<p>java.awt.Color => org.eclipse.swt.graphics.Color<br>
+java.awt.Graphics => org.eclipse.draw2d.Graphics<br>
+
+</p>
+</div>
+<p>Then just do a global find for all of the imports and replace them with nothing. This is a great place for a regexp. Try:</p>
+<div class="literallayout">
+<p>find: import java\.awt\.(.*);<br>
+replace: [nothing]<br>
+
+</p>
+</div>
+<p>You don't have to replace these with the SWT equivalents, just click on the project, right-click and choose "Source:Organize Imports.."
+ By the way, a great way to avoid having to select the right entries in optimize imports and to alert you when you have missed anything is to prevent the awt and swing classes from being used at all. Right-click on project, choose "Build Path:Configure Build Path", go to Libraries tab, open JRE System Library, choose "Access Rules", edit, and then add entries for java/awt/** and javax/swing/**. The code will regenerate and you'll have error markers for all of the stuff that won't work with Escape and Eclipse.</p>
+</div>
+<div class="section" title="Convert color features">
+<div class="titlepage">
+<div>
+<div>
+<h4 class="title">
+<a name="Convert_color_features"></a>Convert color features</h4>
+</div>
+</div>
+</div>
+<p>You can't use AWT colors either so you'll need to replace any colors. AMP provides a convenience classes for Colors called ColorFeature and ColorFeatureConcrete. You can use these or any of the other ways to define SWT colors. For example:</p>
+<div class="literallayout">
+<p>Color.lightGray => ColorFeature.LIGHT_GRAY<br>
+new Color(Math.min(1.0f, (float) (redEnergy + orangeEnergy)), (float) orangeEnergy * .8f, (float) blueEnergy) => <br>
+ ColorFeatureConcrete.create(Math.min(1.0f, (float) (redEnergy + orangeEnergy)), (float) orangeEnergy * .8f, (float) blueEnergy)<br>
+
+</p>
+</div>
+</div>
+<div class="section" title="Change agent color getters">
+<div class="titlepage">
+<div>
+<div>
+<h4 class="title">
+<a name="Change_agent_color_getters"></a>Change agent color getters</h4>
+</div>
+</div>
+</div>
+<p>If you've defined colors through overriding Agents as in most models, you'll need to change the method signature. You could just do a global replace for this one.</p>
+<div class="literallayout">
+<p>public Color getColor( => public Object getPlatformColor(<br>
+
+</p>
+</div>
+</div>
+<div class="section" title="Get rid of image features">
+<div class="titlepage">
+<div>
+<div>
+<h4 class="title">
+<a name="Get_rid_of_image_features"></a>Get rid of image features</h4>
+</div>
+</div>
+</div>
+<p>Escape doesn't support them. In practice they haven't been used a lot. At some point perhaps we'll have nice sprite support instead. :)</p>
+<div class="literallayout">
+<p>public Image getImage() {**} => ""<br>
+
+</p>
+</div>
+</div>
+<div class="section" title="Modify usages of DrawFeatures">
+<div class="titlepage">
+<div>
+<div>
+<h4 class="title">
+<a name="Modify_usages_of_DrawFeatures"></a>Modify usages of DrawFeatures</h4>
+</div>
+</div>
+</div>
+<p>If you've created any of your own draw features, you'll need to change them slightly to accommodate the differences between the AWT and SWT / Draw2D APIs. This should be pretty straightforwrd. For example:</p>
+<div class="literallayout">
+<p>g.setColor(...<br>
+g.fillOval(..<br>
+becomes:<br>
+g.setBackgroundColor(<br>
+g.fillOval(..<br>
+
+</p>
+</div>
+<p>That's about it, though it's probable that we've missed something. Please post a message on the amp newsgroup if you run into any other conversion issues.</p>
+</div>
+<div class="section" title="Configuration">
+<div class="titlepage">
+<div>
+<div>
+<h4 class="title">
+<a name="Configuration"></a>Configuration</h4>
+</div>
+</div>
+</div>
+<p>Instead of using Ant, Escape has really nice support for parameterizing and testing models. See
+ <a class="ulink" href="/wiki/Experimenting_and_Testing" target="_new">Experimenting and Testing</a> (todo). If you do want to work with ant you will need to install the plugins from the Sourceforge download site. (These have dependencies that I didn't want to bother with going through the Eclipse IP process to get in. If for some reason you think these should be part of core Escape let Miles know and I'll take care of it.) Ant has not been tested for Escape so it's not even clear it will work.

+<p>Many models have been created using Ascape over the years, including all of the classic models created at Brookings and some other cool models such as Craig Reynold's Boids and a pretty cool little traffic model, and they've all been converted to run in Escape. They're in Java but you can execute and explore them in exactly the same way as the Epidemic model above. All of the Ascape example models have been converted (a straightforward process) from their intial Ascape incarnations. For licensing reasons (they're BSD, not EPL) we can't host them directly on the Eclipse site. You can get the projects in two ways:</p>
+<p>Once you've downloaded the projects, open up the src folder and navigate to the Java files for the actual models. For example, to run Conway's Life, you'll want src/edu.brook.life.ConwayLife. Right-click on the Java file and select "Execute". There are many models to explore! (It's not always obvious which Java files are for models, so you may have to poke around a bit. We need to put together a catalog here. Another nice opportunity for user contributions.)</p>
+<p>These are SVN projects in the sourceforge SVN. For help, see

<td>Launching AMF and Escape models is easy. When an AMF file is selected -- in any of the perspectives -- the toolbar and Application menus are updated to reflect the file you've selected and provide convenient access to other functions. For example, when we click on a metaabm file in the package explorer, model execution buttons appear in the toolbar. If you right-click on a file a pop-up menu appears like the one to the far right -- in this case we're selecting the "Execute Headless" option. To launch a model, just select one of the options. (Note that the execution framework doesn't know whether your code exists in an Escape project or another target project. If you attempt to execute a .metaabm model in an Ascape project for example, you will get an error.)</td>

+<p>Note that there are no dependendencies on AMF, and therefore EMF or any other modeling technologies to do Java development for Escape or for running generated models within Escape. The deployment environment can be quite light-weight. Simply install the AXF, AGF, and AMP Escape features. You can build from source but in that case you'l need to launch a self-hosted runtime, so it's best to simply install from the update site if you're not actually doing AMP development.</p>
+<p>Escape is

+</div>
+<p>If you're like many Java developers, you might find point-and-click interfaces a bit lame. Personally, I've changed my tune in this, and I now define all of my ABM models from the editor, saving Java for truly specialized tasks. But even without generation of agent behavior, Acore can be a really valuable tool, as the GIS example shows. The way to look at metaABM is as a way to compose your overall model and automate the tedious parts. Apart from Java generated code, the AMF meta-model maintains a number of very useful artifacts. For example, the Repast Simphony target maintains model.score and all of the model.rs component. Generally, AMF should save time and hassle while making your models far more transparent even if you never use the Actions component to define agent behavior.</p>
+<div class="section" title="Method Action">
+<div class="titlepage">
+<div>
+<div>
+<h3 class="title">
+<a name="Method_Action"></a>Method Action</h3>
+</div>
+</div>
+</div>
+<p>As explained in the action section, you can simply create a "Method" act with hand-written Java code. This option is nice because all code is contained within the AMF file. But it can be difficult to maintain large blocks of Java code as you aren't using a Java editor to edit the Java code itself. One way to get around this is to create your code in the generated Java method and then copy it into the Method action. Note one imporant issue here -- you'll generally have to fully qualify your Java references as you won't be able to change the imports statements directly. </p>
+</div>
+<div class="section" title="Protected Code Regions">
+<div class="titlepage">
+<div>
+<div>
+<h3 class="title">
+<a name="Protected_Code_Regions"></a>Protected Code Regions</h3>
+</div>
+</div>
+</div>
+<p>You can mix and match Action behavior with Java and generated code with POJOs. One way to do this is through using protected regions. Select the agent you want to create protected methods for and then select "Generate Protected" from the "Mode" property. Now, create actions just as you have before, or use your existing ones. On code generation, open up the relevant java file and examine the methods that have been created. </p>
+<p>
+
+</p>
+<div class="mediaobject">
+<img src="images/pojo/ProgrammingPojoGenerateProps.png"></div>
+<p>
+
+</p>
+<p>You can put whatever you want within the PROTECTED REGION comments and those changes will be preserved when the model is regenerated. You can create a schedule, rule or watcher, maintain custom code for the actual implementations, and still have the model adapt to changes in the underlying data structure -- if for example you want to import a modified shape file.</p>
+<p>

+<a name="Interface_and_Base_Class_Generation"></a>Interface and Base Class Generation</h3>
+</div>
+</div>
+</div>
+<p>Another approach which can be more robust is to generate the basic model stubs (like an abstract base class except that it isn't abstract) and then override your model with implementations. AMF provides support for generic skeletons and interfaces.</p>

<p>In this manual we provide an in-depth understanding of what goes into an Agent Model, how you can use the Agent Modeling Framework and related tools to design one and present tutorials to get you started. But before going into details, let's take a quick overview at what agent-based modeling is is and how the Agent Modeling Framework can help you to develop models for ABM or other problem domains.</p>
<p>We hope you enjoy using the tool, and we look forward to your comments and feedback and most of all participation!</p>

-<p>Existing scientific models are very good at representing relatively simple systems, but generally speaking aren't very good at representing complex systems. The world is full of complex systems, and our misunderstanding of these systems has prevented us from addressing many of the key challenges facing the world, including the global financial crisis and climate change -- in fact once could argue that our misunderstanding of these systems has strongly contributed to these crises.</p>
-<p>Agent-Based Models (ABMs) seek to represent important real-world dynamics by designing communities of software agents that mimic real entities. Rather than make simplifying assumptions about such systems and then representing them in equation form or as off the shelf algorithmic constructs, the ABM researcher aims to identify key agent state, interaction spaces, and behaviors. Agents are then "let loose" on our computers and we explore what happens next. The computational horsepower exists today to simulate large numbers (e.g. >>10) of interacting, adaptive and autonomous agents but often desktop computers are all we need to explore significant domains. ABMs have been designed to represent all kinds of important natural systems, at scales reaching from cellular mechanics to international trade and are being used to solve truly hard problems in government, business, and academia. ABMs are not a solution to every problem, but they can help us to appreciate and gain unique insight into many systems, and often they can help us to come up with better practical decisions than we might using classic approaches.</p>

+<p>AXF and AGF provide a number of features based around Eclipse technologies such as GEF, GEF3D, BIRT Charts and Zest. For example, AGF supports dynamic visualization of objects in space, and AXF supports managed UI and headless execution for models of any kind. There isn't currently any general documentation for these features, but we encourage you to look at the APIs and at Escape's implementation of them. They're straightforward and can be useful for a variety of general science platform needs.</p>

+<p>Many kinds of objects share characteristics of ABM agents -- after all, software agents are used in many other contexts. The Agent Modeling Framework meta-modeling support is potentially suitable (or extendible) for a number of approaches outside of ABM; for example business rules, object interactions, systems dynamics models and traditional discrete event models. Similarly, AMP execution and graphic support can be used for modeling natural systems but could also be used to manage other software agents -- for example independent reasoning tasks or dynamic visualization support.</p>

-<p>Existing scientific models are very good at representing relatively simple systems, but generally speaking aren't very good at representing complex systems. The world is full of complex systems, and our misunderstanding of these systems has prevented us from addressing many of the key challenges facing the world, including the global financial crisis and climate change -- in fact once could argue that our misunderstanding of these systems has strongly contributed to these crises.</p>
-<p>Agent-Based Models (ABMs) seek to represent important real-world dynamics by designing communities of software agents that mimic real entities. Rather than make simplifying assumptions about such systems and then representing them in equation form or as off the shelf algorithmic constructs, the ABM researcher aims to identify key agent state, interaction spaces, and behaviors. Agents are then "let loose" on our computers and we explore what happens next. The computational horsepower exists today to simulate large numbers (e.g. >>10) of interacting, adaptive and autonomous agents but often desktop computers are all we need to explore significant domains. ABMs have been designed to represent all kinds of important natural systems, at scales reaching from cellular mechanics to international trade and are being used to solve truly hard problems in government, business, and academia. ABMs are not a solution to every problem, but they can help us to appreciate and gain unique insight into many systems, and often they can help us to come up with better practical decisions than we might using classic approaches.</p>

-<p>Many kinds of objects share characteristics of ABM agents -- after all, software agents are used in many other contexts. The Agent Modeling Framework meta-modeling support is potentially suitable (or extendible) for a number of approaches outside of ABM; for example business rules, object interactions, systems dynamics models and traditional discrete event models. Similarly, AMP execution and graphic support can be used for modeling natural systems but could also be used to manage other software agents -- for example independent reasoning tasks or dynamic visualization support.</p>

The AMF Acore meta-model is similar to EMF Ecore and defined in Ecore, but provides high-level support for complex agents.AMF generates complete executable models for Escape, Ascape and Repast Simphony, as well as Java Skeletons and Interfaces, JUnit test cases and documentation and is easily extensible to support additional targets.

-<p>The execution framework provides services and UI for model management, execution, and views. Arbitrary toolkits can easily integrate with Eclipse and AXF by implementing pluggable providers like engines, agents and view parts. AXF is not just for ABM -- anyone who needs support for executing, managing and visualizing collections of objects may find it useful. AXF user tools are covered extensively in the User Guide, and the forthcoming Platform Developers Guide will provide information about integrating AXF in your own tools.</p>

-<p>The graphics framework extends GEF, GEF3D, Zest, and the BIRT charting engine to support real-time visualization of and interaction with agent models. AGF currently provides support for 2D, 2 1/2 D. and graph structures, and will be extended to 3-D, GIS and others. As with other AMP components, the AGF design focus is to provide an extensible infrastructure so that platform adopters can easily create their own view and editor parts. AGF user tools are covered extensively in the User Guide, and the forthcoming Platform Developers Guide will provide information about integrating and extending AGF in your own tools.</p>

-<p>Escape is an exemplar ABM toolset. It's based on Ascape, which has been in use for more than 10 years. The core API is very stable, and that should give users a way to explore the features of AMP without concerns about keeping in synch with the rapidly evolving AXF /AGF API. It allows modelers to code in Java and/or generate models with AMF and then execute those models within the same development environment. Escape is the primary target for most of the models in this guide. Those users interested in writing code directly to the Escape API can refer to the Programmer Guide.</p>

-<p>AXF and AGF provide a number of features based around Eclipse technologies such as GEF, GEF3D, BIRT Charts and Zest. For example, AGF supports dynamic visualization of objects in space, and AXF supports managed UI and headless execution for models of any kind. There isn't currently any general documentation for these features, but we encourage you to look at the APIs and at Escape's implementation of them. They're straightforward and can be useful for a variety of general science platform needs.</p>

-<p>In this section we present the design of the Agent Modeling Framework and explain how it can be used to create models that are transparent, composable and adaptable. Fundamentally, an agent-based model, or "ABM", is composed of five pieces: Agents and Context Agents, Attributes, Spaces, and Actions. The first three refer to structural components, whereas Actions define behavior. Agent models also have styles, which are a special kind of Action used to determine how to portray an agent in a visualization. Finally Actions make use of Functions. We'll describe of these components in a separate section.</p>

-</div>
-</div>
-<p>The Eclipse Platform provides many unique features that make it ideal for an ABM platform. AMF provides easy to use and powerful tools and techniques for designing Agent-Based Models, including a common representation, editors, generators and development environment.</p>
-<p>The Agent Modeling Framework (AMF) provides high level representations for common ABM constructs, and introduces novel ways of representing agents and their behaviors. As detailed in other documentation sections, the Agent Modeling Framework and related tools have been designed to allow researchers to explore complex models in an intuitive way. One of our major design goals has been to create tools that non-programmers can use to create sophisticated models. It has been our experience that using Model-Driven Software Development (MDSD) techniques increase productivity for all developers regardless of skill level. </p>
-<p>The foundation of the Agent Modeling Framework is "Acore". The current version uses an interim version of Acore called "MetaABM". We refer to the AMF models as "meta-models" because they are used to define
- <span class="italic">how</span> Agent-Based Models are themselves modeled. For those familiar with Eclipse Model-Driven Development tools, AMF is analogous to EMF but is targeted toward the design and execution of models composed of agents. Acore and MetaABM are defined in Ecore but provide a more direct and high-level ABM representation of agents, including spatial, behavioral and functional features sufficient to generate complete executable models for the target platforms. AMF is fully integrated with the Eclipse IDE platform, but Acore models themselves need have no dependencies on any particular technology beyond XML/XSD.
- </p>
-<p>Models designed in AMF are transparently converted to Java code for leading Agent-Based Modeling tools, such as the Escape tools which are included in AMP and allow direct execution of models within the AMP environment, and Repast Simphony, another popular Java based ABM tool. These tools create Java code that can then be compiled, executed and event modified in these environments just as with any other Java program. AMF's generative capability is designed to be pluggable and modular so that other developers can create AMF generators for their own tools. In fact, targets can be designed that have no inherent dependencies on Eclipse or even on a traditional platform.</p>
-<p>The Acore / MetaABM meta-model is made up of three main packages. This is all based on MetaABM, and while names and important details will change for Acore, the core design should be quite similar.</p>

-<p>The basic structure of an agent-based model can be quite simple. While there are many subtle complexities -- beyond the scope of this manual -- we can construct most models following some straightforward and elegant design principles. And in fact, one of the main goals of the Agent Modeling Framework is to provide a consistent framework that can support using those principles to support the creation of models that can be easily understood, shared, and that can be used interchangeably as components in other models.</p>
-<p>Unlike the approach of a traditional Object Oriented environment, the dominant organizing principal for agents within AMF follows a compositional hierarchical model, not an inheritance model. (Inheritance-like behavior will be supported in forthcoming versions of Acore, but in a more sophisticated, flexible and dynamic way than is supported by traditional programming languages such as Java.) Contexts -- also referred to as "Swarms" or "Scapes", are simply Agents that are capable of containing other agents. With this basic construct -- known as a Composition in design pattern language -- agents are able to contain other agents.</p>

-<p>Everything represented in an Acore model needs to be referred to in some way. Just as software classes have names, Acore provides a way to label and describe every entity, but in a richer and more maintainable way. All entities in Acore -- including Actions and Functions which we describe in the next two sections -- have a number of shared values.</p>

-</div>
-</div>
-</div>
-<p>A reasonably short, human readable name for the agent. For example, "Timber Wolf", "Exchange Trader" or "Movement Probability". These should be defined so that they fit in well with auto-generated documentation. Note that Labels must be unique throughout the model. (This may change in future releases for Action names.) If you try to provide an object with a name that is already in use, "Copy" will be appended to the end of the name. </p>

-</div>
-</div>
-</div>
-<p>An ID is an identifier that can be used to represent the object in a software program. This means that it must follow certain rules such as no-spaces or non alpha-numeric characters. The editing tools will help make sure that this value is legal. Note that when you enter a label, a legal ID is automatically created for you! Usually you won't need to change this, but you might if for example you want the value to match up with some database or other external representation. So reasonable values here might be "timberWolf" or perhaps "MVMNT_PRB" if say you're trying to match up to some old statistics records you have. (Note that currently IDs by default use "camel case", i.e. "thisIsAnExampleOfCamelCase" to match with Java variable naming conventions, but this is likely to change.) Like labels, IDs need to be unique across the model, and the editing tools will assign a different id if you attempt to give two entities the same id.</p>
-<p>And most entities also define:</p>

-<h6 class="title">
-<a name="Description"></a>Description</h6>
-</div>
-</div>
-</div>
-<p>A complete textual description of the object. Don't overlook this -- it is the most important part of your model. The description will show up in your auto-generated html documentation, software documentation and even in your running model. You should include enough information that model users will understand what the entity is for and what it does without referring elsewhere. This is also where any attributions and references should go. You can put html tags in here -- such as href's to external papers, but keep those to a minimum as they won't be rendered as html in all contexts.</p>

-<p>An Agent is simply a software object that has autonomous behavior and (generally speaking) exists within some set of spaces. By autonomous, we mean that agents make the choice about when and how to execute a behavior, as opposed to have that controlled from "above", so to speak. Like any software objects, agents have attributes (fields) and actions (methods) associated with them.</p>

-<p>As detailed above, agents also form the basic structural component of an agent-based model. To get an idea for how this works, have a look at the "EpidemicRegional.metaabm" model. Note that in future releases, we will probably refer to Contexts as "Scapes".</p>

-<p>Agents need some way to represent their internal state. For example, an agent in an economic model might have a wealth attribute, and an agent in an ecology model might have a quantity of food and a particular vision range. These states are represented as attributes just as all software objects do. In an agent model, we keep richer information about these attributes and generally represent them at a higher level. For example, rather than specify that a real value is a "double", a "float" or a "big number", we represent them as "Reals" so that they can be implemented and tested in different environments. This might allow us for instance to ensure that a model's behavior is not dependent on a particular machine implementation of floating point arithmetic. Also, note that attributes only represent so-called "primitive" values -- that is, actual measurable features of a particular agent but not an agent's relationship to other agents or objects. See the discussion about networks for more on this key topic.</p>

-<p>Attributes are single values that a given agent contains. For example, an agent might have an "Age" attribute. In this section we go over the values you can set for the attributes. For those with a tecnical bent, note that we are technically describing the meta-attributes for the meta-class "SAttribute". But it is far too confusing to refer to the attributes of attributes! So we'll just refer to the attributes that any of our model components as "values".</p>

Generated artifacts and documentation will be much clearer, and you'll be able to easily modify the model later if for example you discover that there are more than two potential gender categories that are relevant to your model.</td>

- <td>A continuous number value. While these are typically represented in software as floating point numbers, they can conceivably represent numbers at any arbitrary precision and in any scheme.

For example, you might use it to store some kind of input coding from data that is then converted into an object state. Or it could simply be an agent's name. But theoretically (though this is not currently supported) one could imagine a symbol using an idiogram, an icon or even a sound that identifies or represents the agent in question.</td>

-<div>
-<h4 class="title">
-<a name="Spaces_2"></a>Spaces</h4>
-</div>
-</div>
-</div>
-<p>All contexts can contain spaces. Spaces provide an environment in which agents can have a physical or notional location and upon which they can interact with one another and their environment. Agents can exist in more than one space at a time, and a given agent need not exist in every space. (Note that this is different from the Repast Simphony notion of projections, though the two representational approaches are generally compatible.) Agents need not represent explicit, "real" spatial structures such as a landscape, though this is of course the most common use. They can also represent relational and state information, such as a belief space or a social network. There are four kinds of space represented:</p>
-<div class="section" title="Space (Continuous)">
-<div class="titlepage">
-<div>
-<div>
-<h5 class="title">
-<a name="Space_.28Continuous.29"></a>Space (Continuous)</h5>
-</div>
-</div>
-</div>
-<p>In the modeling tools, we simply refer to this as a "Space" as it is represents the general concept of a space. A space is simply something that contains objects with certain locations and extents and has a certain number of dimensions. The space is continuous, in the sense that objects can be placed anywhere with arbitrary position. Spaces hold attributes, which simply define their dimensions-- see below.</p>
-<div class="section" title="Border Rule">

-<div class="variablelist">
-<dl>
-<dt>
-<span class="term">Periodic</span>
-</dt>
-<dd>
-<p>When encountering an edge, the agent will treat the space as wrapping around to the other side of the space. For example, if the agent at location {1,2} (0-based) within a Moore space (see grid discussion below) of size {10,10} is asked to find some other agent within distance 3, the agent look in the square defined between {8,9} and {4,5}. An agent asked to move beyond the confines of the space will simply stop when it reaches the edge. You can imagine this as taking a piece of graph paper and connecting the opposite edges. You can't actually do that with paper, but if you could you would have a toroidal (donut) shape in three dimensions defining the shape in two.</p>

-<h6 class="title">

-<h6 class="title">

-</div>
-</div>
-</div>
-<p>This value determines what constitutes a region within a particular distance from the agent. The value for this is often critical in obtaining particular behavior from a model, and shouldn't be overlooked. There are three possible values:</p>
-<div class="variablelist">
-<dl>
-<dt>
-<span class="term">Euclidean</span>
-</dt>
-<dd>
-<p>The distance between any two cells is taken to be the "real" distance. For example, if an agent was within a chess board, and we wanted to find all agents within distance three of it, we could determine that by taking a string of length 3, tacking it to the center of the source square, and including all cells whose centers we can reach with the other string end. Note that although Euclidean space may seem the most reasonable neighborhood configuration to choose, this really isn't the case. Euclidean space is continuous whereas grid space is discrete, and mapping the two to each other can create unexpected issues. Still, this is a good choice for models representing notional real spaces.</p>
-</dd>
-<dt>
-<span class="term">Moore</span>
-</dt>
-<dd>
-<p>Here, the distance between any two cells is defined by the number of edge
- <span class="italic">or</span> corner adjacent cells crossed to get between them. To continue the chess board analogy, this is the set of moves that a king can make. Note that this does not map well to real space at all, as a cell at distance 1 in a moore space is at distance sqrt(2) in "real" space.

-<a name="Network"></a>Network</h5>
-</div>
-</div>
-</div>
-<p>A network represents a set of relationships between agents, in a graph structure. The concept is pretty simple, but note that a network is actually a critical part of many AMF models. This is because we use networks to represent any kind of references between agents. You may have noticed in the discussion about attributes that there is no generic "object" type for an attribute. In fact, attributes only contain primitive values. So we will use networks to do the kinds of things that we would often use object references for in a traditional Object-Oriented model. For example, if an agent is a member of a family, rather than have that agent have a member attribute of "family" with a reference to the "Family" object, the modeler would create a "Family Members" network and connect agent's to their families as appropriate. This implies that network members can contain members of many different types.</p>
-<p>A network has only one value to specify:</p>

-<h6 class="title">

-<p>This indicates whether connections between agents are one-way or two-way. If this value is false, then if a connection is made between an agent A and an agent B, and agent B searches within distance 1, agent B will find agent A. If this value is true, agent A can find agent B, but agent B can not find agent A. (Unless of course some other path leads B to A.)</p>

At runtime, (model-level) Context instances defined in a (meta-level) SContext will contain (model-level) agent instances of the defined (meta-level) SAgent. This sounds more complicated than it is, so let's look at a simple example. Suppose we create a new Context, and give it a label of "Wiki Example". Within that Context, we create an Agent and give it a label of "Individual" and another Agent with the label "Block".

-</div>
-</div>
-</div>
-<p>Actions allow the definition of behavior for agents at a very high level. You can think of actions as being analogous to methods in a traditional object-oriented model but that analogy only goes so far. In the same way that methods are defined as part of objects, actions belong to particular agents. (Though even more expressive ways of defining actions are contemplated in future releases.) In the next section we go into detail about what Actions are and how they can be used to define all agent behavior. They are also conceptually more challenging as unlike with structure they have no direct analogies to past agent representations.</p>
-<p>An action provides simple, well-defined details that a model can use to determine what steps to take in model execution. That definition seems general enough to be almost useless, but its important to understand that an action is not equivalent to an instruction, a method or a query. In fact, actions can have aspects of all of these. But an action is not in itself an instruction specifying exactly
- <span class="italic">how</span> the modeling engine should do something -- instead an action represents
- <span class="italic">what</span> the modeler intends for the agents to do. (Technically, we might say that Actions takes a "declarative" approach instead of an 'imperative' approach, but that's not quite true, because actions do allow us to define behavior in a richer way than most declarative approaches, and many action constructs map directly to imperative approaches.)
- </p>
-<p>Actions are connected together in a series of sources and targets. (Technically, an acyclic directed graph.) In an abstract sense that is similar to the way any programming language is defined although that structure isn't usually obvious because of the constraints of textual representations. But unlike a typical programming language, in Actions it is not the execution thread (the processor) that moves from one instruction to the next, but the result of the previous action. In this way, action results "flow" from the output of one action into the next action.</p>
-<p>Why are these distinctions between traditional Object-Oriented and the Action approaches important? They give us the advantages of simplicity, clarity and flexibility that
- <a class="ulink" href="/wiki/http://en.wikipedia.org/wiki/Dataflow_programming" target="_new">data-flow approaches</a> like spreadsheets and some query languages have, but with less restrictions. At the same time, they can bring us much of the power and expressiveness of
- <a class="ulink" href="/wiki/http://en.wikipedia.org/wiki/Functional_programming" target="_new">functional languages</a> like Lisp or
- <a class="ulink" href="/wiki/http://en.wikipedia.org/wiki/Logical_programming" target="_new">logical languages</a> like Prolog, but without the level of complexity and obscurity that such languages can have.
- </p>
-<p>We can get a better idea for how Actions work by thinking about how a spreadsheet works. In a spreadsheet, we might define a cell A that adds up a row of data, say "Income". We might define another cell C ("Profit") that takes A and adds it to another cell B that adds up another row of data ("Expenses"). Now, if we change a value in any of the rows, all of the other rows are added up and we get the results in A and B updated automatically. We never had to write code that said something like "for each cell in row X, where...". In fact, we don't really care
- <span class="italic">how</span> our Spreadsheet program adds up the numbers -- it could have added them all up at once but in backward order, or stored a running total somewhere and updated just the difference in value for the cell we changed -- what we care about is
- <span class="italic">what</span> the result is, and whether it is correct.
- </p>
-<p>But Actions are much more powerful than a spreadsheet, because what is flowing from Action A to Action B is not just a number, but any model component such as a space or a set of agents that we need to use in target actions.</p>

-<td>Before getting into the details of how each Actions work together, or the various kinds of Actions, it will be helpful to take a broad overview of how they all fit together. As discussed above, actions are strung together in a sequence or flow. They're always composed of two parts, though those parts can be assembled and intermixed in many different ways. First, we search for a collection of agents, and then we do something with that selection. We refer to these two parts as Selections and Commands. (For the technically minded, another useful way of looking at the Actions approach is as a Query Transformation language, as with SQL and Stored Procedures. Except again, the results of the queries along with the transformations flow through from one query to the next.) Selections find the agents we want to do something with, and the commands do it. We need some way to start the whole chain of actions off, and so we have a kind of Selection called a Root Selection, or simply a Root. Secondly, we need some way to actually make the agents exist in the model in the first place, so we have a Create Agents action. Finally, we have special commands called builders that allow us to create the spaces that the agents will occupy. The various actions are discussed in depth in the Details section.</td>

-<p>First, let's look at how actions define the basic path that agents take during a model run. As with any programming language, the path we take through the program specification is what determines our state when we get there. In a pure object oriented program, the path just defines the control flow -- what we are doing. The actual state of our model is defined within the object itself. If we call a method B from another method A, we'll be relying on method A to set the values that we need into the object state itself. In a purely functional program the path defines how we are going to deal with whatever has been explicitly passed in to a function that has been called, that is the function parameters. In fact, most languages such as Java combine aspects of both approaches.</p>
-<p>In Actions, the path itself implicitly carries all of the context of prior execution with it. This means that we don't have to worry about storing context in the object -- as we would in an object-oriented language -- or passing the correct values from one method call to the next as we would in a functional language. Instead, Actions can use the implicit context of the path of flow to determine what the current state of execution is.
- An important aspect of the Actions design is that loop structures are not allowed -- that is, flows are acyclic. An action can never have an ancestor target (that is targets, targets of targets, etc..) that has as one of its ancestors that same action. As you'll see, actions don't typically
- <span class="italic">need</span> loop structures. By far the most common use of loops in conventional programming langauges is to loop through collections of objects. As selections (see below) refer to the entire collection of agents, any actions on a selection apply to all members of that collection. Recursive structures are needed for some particular usages and will be supported in future releases, but not through an explicit looping construct.

Then, we might add a series of Query and Logic Actions to define the specific agents that we are interested in. These are all part of the Selection. Next, we might define a series of Commands to determine what to do with those agents. Or, we could use the result of that selection to immediately define another selection, for example if we are searching for an agent that is near another agent.

-<p>In the following example, we've defined a set of actions and their relationships. We have a selection, a few queries and a couple of logic operators leading to a Set Action. We'll describe in detail below how Logic Actions are used in conjunction with other actions to assemble any kind of query structure needed. But for now, we'll focus on the control flow itself.</p>
-<p>
-
-</p>
-<div class="mediaobject">
-<img src="images/actions/ActionsFlowSimple.png"></div>
-<p>
-
-</p>
-<p>As you have probably already guessed, the agents that have the Set Action applied to them could take one of two paths through the Action flow. Readers with experience with programming or formal logic will note that this looks just like a parse tree, and while that's basically what it is, there are important differences. For example, if we looked at the following structure as a definition of control flow for a single agent we'd take them to be equivalent. Both would evaluate the statement (Query 1 AND Query 2) OR Query 3 for each agent.</p>
-<p>
-
-</p>
-<div class="mediaobject">
-<img src="images/actions/ActionsFlowUnion.png"></div>
-<p>
-
-</p>
-<p>Within Actions in many cases these two approaches will also act equivalently. If we are simply setting a value, it doesn't matter how an agent gets to that Set Action, as long as it gets there. All sources that flow into a given target Action act like a logical union since any of the paths might reach that target. But note that we have two flows moving in parallel in the flow on the right. What happens when the conditions for
- <span class="italic">both</span> branches are true? As the set of agents flow through each branch the Set Action on the left will be evaluated once, while the one on the right will be evaluated twice. Again, this often ends up with the same behavior, but not always. If for example, the evaluate Action uses the value of the attribute that we are setting as input, we can get different results. Of course, you can write code in any language that accomplishes the same thing, but the code will look quite different. For example, if we wrote the same basic logic in Java, in the first case we'd have something like:
- </p>
-<div class="literallayout">
-<p>if ((query1.evaluate() && query2.evaluate()) || query3.evaluate()) {<br>
- doSomething();<br>
-}<br>
-
-</p>
-</div>
-<p>In the second we'd have:</p>
-<div class="literallayout">
-<p>if (query1.evaluate() && query2.evaluate()) {<br>
- doSomething();<br>
-}<br>
-if (query3.evaluate()) {<br>
- doSomething();<br>
-}<br>
-
-</p>
-</div>
-<p>This is a simple example, but with multiple branches such code design issues can quickly grow complex. The flow approach allows us to express things in a way that is often more natural and expressive. The important thing to keep in mind when desiging action flows is to see the flow as representing a selection of agents moving through streams independently. In the Actions example we expressed both approaches in nearly the same way, except in the case on the left we used a Union Action to bring the two branches of flow back together.</p>

-<p>Selections are a key concept in Actions. Put simply, selections define what we are searching for and where. They are defined by a combination of Select, Query and Logic Actions. Each time we create a new Select Action, we define a new selection. Queries can be used to further refine selections either immediately after or later in the Action flow, as described in the next section. Logic Actions are used to combine and organize the Action flow defined by Query Actions. In order to understand how these three pieces work together, we need to understand the idea of selection boundaries.</p>
-<table id="N10321">
-<tr>
-
-<td>A selection boundary determines the set of selection actions that are used to determine what agents to apply target actions to. For example, in the following diagram, we can see the extent of the boundary for a straightforward selection.</td>

- <td>
-
-<div class="mediaobject">
-<img src="images/actions/ActionsSelBoundary2Parts.png"></div>
-
-</td>
-
-</tr>
-</table>
-<p>But boundaries can be defined for a group of actions by a Query Actions as well. This is because Query Actions can be directly part of a selection definition, but they can also refine selections. We'll see how that works below. So where does one selection boundary end and the next one begin? The simple rule is that the end of the boundary is defined for a given Action by the place where:</p>
-<div class="orderedlist">
-<ol class="orderedlist" type="1">
-<li class="listitem">
-<p>A Query Action is not followed by a Logic Action, or</p>
-</li>
-<li class="listitem">
-<p>A Logic Action is not followed by another Logic Action</p>
-</li>
-</ol>
-</div>
-<table id="N10350">
-<tr>
-
-<td>In other words, as soon as a Logic Action occurs in a path leading to an Action, any following Query will define a new boundary, as shown in the example to the right. </td>
- <td>
-
-<div class="mediaobject">
-<img src="images/actions/ActionsSelBoundary11A.png"></div>
-
-</td>
-
-</tr>
-</table>
-<p>Note that we refer to "Selection 1" and Selection 1A". This is because Selection 1A is a refinement of Selection 1 along its particular path of flow. When a query appears for the same selection but past a particular boundary, you can think of it as a sort of filter on the selection contents. We don't have a "Selection 2" here because any Actions that refer to "Selection 1" along the current path of flow will be acting on the selection defined by Selection 1 and Selection 1A.</p>
-<p>These rules allow actions to be defined in the simplest possible way, but it is important to understand their implication as they result in behavior that can be different from what someone used to and imperative programming environment such as Java might expect. In a simple case the distinction might not matter. For example, if we are using a Query 1 to test whether an agent's attribute a == x and attribute b == y, we would get the same outcome if we placed intersected the queries as if we simply put them in sequence. Internally we would actually be searching for agents with a == x, and
- <span class="italic">then</span> taking those agents and choosing those agents with b==y, but the outcome would be the same. But consider a more sophisticated case, where we are searching for neighboring available cells.
- </p>
-<p>
-
-</p>
-<div class="mediaobject">
-<img src="images/actions/ActionsSelBoundaryComplex.png"></div>
-<p>
-
-</p>
-<p>In the first case, we execute a search for all agents that meet the two criteria. This means that if there are
- <span class="italic">any</span> neighboring cells which are available, we're guaranteed to find one (random) cell. In the second case, we first search for all cells that are neighbors. This will match any agents that include both available and non available agents. Now, at this point since our search returns one agent (in the current AMF design -- richer behavior will be supported in the future) the randomly selected agent could be either available or not. So in the second case, we might end up with no cell to move to, and thus make no move at all. This then becomes an important aspect of model design. For example, if one were defining a model where neighbors played a game with each other, one might want to instruct agents to play the game only with neighbors that have a certain wealth threshold. In the real-world situation that we are modeling, we might simply search for neighbors who are over a given wealth threshold and then play the game with them. This would imply that information about other agent's wealth is open knowledge. Or, we might simply select a random neighbor, and ask that neighbor to play a game with us. Upon discovering that our neighbor does not meet our wealth criteria, we would then choose not to play with them. Here we are modeling a cost in time to obtain information about another agent's wealth, because we might miss an opportunity to play the game with another agent on that round.

And as we discussed in the selection section, the selection and its boundaries determine what agents we will be working with at any given evaluation point in the flow. Consider the example to the right. As we'll see in the detailed explanation of each Action below, Transformation Actions such as Move or Connect take multiple selections. The first selection defines the set of agents that will be performing the action. In the case of a Move agent, this refers to the mover. The second selection, which for Move we call "destination", refers to the selection that will be receiving the action. In the case of movement this is the agent or location that the Rule agent will be moving to. If we follow the flows through, we can note two important outcomes of our model design -- a Rule agent might move twice if it meets the criteria for both the blue path and the red path and that it might move to a different location each time.</td>

-<p>As we discussed above, when we refer to a Select, we're actually referring to the selection as a whole leading up to the current action. The Select Action itself is used to define what we are searching for (Agent), where we are searching for it (Space), and from whose perspective we are doing it (Selection). Create Actions are a sepecial kind of Select Action that are used to create agents. See the decription in the Builders section below for more information.</p>

-<p>The selection that we are searching "from". This seems to be the concept that new users have the most difficulty with, but it is key to understanding how Actions works. Just as with any other Action -- a Move command for example -- a selection needs to know what set of agents that it is working with. For example, if we want to define a selection B that finds the cells neighboring a rule B's agent, we would set selection B's selection to A.</p>

An agent must be specified unless we are searching within a continuous space, in which case this value should be empty, and the result of the selection will represent some location in that space.

-<p>A Query represents a concrete criteria for our search. The name is a bit confusing because of potential for confusion with a generic query. Queries -- along with their cousin Evaluators -- define a function that is evaluated and that can take Agent attributes and the results of other Actions as input.

But as we've seen above, it is important to understand that there are important differences between Logic Actions and typical programming logic. Most importantly, they apply not to individual agents per se, but to the set of agents that move through them.

A Build Action executes once for each context before any initialization actions occur for any children agents of that context.

-<p>A Watch action is executed any time the watched value is set for any agent. Note that the Action will be triggerred even if the state is simply set back to the value that it already has. It is important to be careful about creating Watches that might set the values of other Watch actions which might in turn trigger this watch. To clarify, if a modeler creates a Watch A for attribute a, and creates a target Set for it for attribute b, and Watch B is watching attribute b, then if Watch B has a target Set for attribute A, a circular execution could occur. This would cause the model to get stuck in its current iteration. To help model developers avoid this case, a warning will be provided if such a set of circular watch dependencies is created.</p>

-<p>Builders are a special category of actions that are used to create spaces. They should not be confused with the Build Action itself which is a root selection that defines the time at which builder actions should occur. Generally speaking, specific Builder Actions for spaces and Create Actions for agents are targets of Build Actions.</p>

-<p>Agents are crete using the Create Agent action. The Create Agent Action is actually a special kind of Select Action that is used to actually create agents rather than simply search for them. Other than this capability, a Create Agent action can be used just like any other action except that Query and Logic actions aren't needed or genrally appropriate as this action defines a set number of agents to perform an action against. Create Agent actions have the special feature of being usable from the containing context, so that contexts can create initial agent populations before any agents exist within the context to perform actions against. But they can also be used directly within agent rules, for example to create a child agent as the result of a reproducation rule. Note that Initialize Actions are
- <span class="italic">not</span> performed on agents that have been created within a model during regular (non-initialization time) execution. If the model creates actions during the regular model run, any state initialization should be handled by the targets of this action directly. (Naturally, if the enclosing context is used to create agents at the beginning of a model run, then the Initialize action is used as part of the normal model life-cycle.)

The available shape types are:</p>

-<span class="term">Line</span>
-</dt>
-<dd>
-<p>A single line within a continuous space. Technically this represents a line segment as it is expected to have a beginning and ending point.

-<span class="term">Polygon</span>
-</dt>
-<dd>
-<p>A region within a space defined by an arbitrarily large set of line segments. Potentially this could be used to refer to polyhedrons in three-dimeensional space, or even more genrally as polytopes, but this is currently not supported by any AMF target implementations.</p>

Future AMF implementations are likely will provide a different mechanism for instantiating and importing network structures either within the network defintion or through other Action definitions. Instead of using this feature, modelers should create specific networks by building them up with Connect Actions for indivdual agents. For example to create a small world netowrk, a modeler might create random links between agents and then replace or augment those connections.</p>

-<p>The Method action supports inclusion of arbitrary code within a generated method. Generally, this will be Java code as all of the current target platforms are Java-based but there is no technical requirement that it must be. For example, if a target has been developed to produce code for Swarm running on an iPad (and no, there are no current plans to support such a thing, though it would certainly be cool!) then the modeler could define Objective C code for the method.</p>
-<p>Please note that the Method Action should be avoided whenever possible. You should consider using it only in the case where there doesn't appear to be a way to construct equivalent functionality using the native Actions framework, such as when interfacing with third party APIs. The aim of Actions is to provide the most general support for Agent Modeling possible without compromising the core design. Any use of native Java code strongly limits the set of platforms that your model will be able to generate code for and prevents you from using the AMF edit tools to explore the model behavior. In the case where you wish to construct a model feature and believe that it isn't possible or practical to do it with Actions, please contact us (see support section) so that we can suggest how you can accomplish what you want within Actions. If that is not possible, we'll consider developing new features that will support what you want to do.</p>
-<p>On the other hand, you may simply wish to use the Agent Modeling Framework to build a scaffolding for your model -- perhaps using your own custom Java framework for example -- and Method would be a good way to accomplish that. Also, note there are a number of other approaches to mixing hand-crafted Java together with AMF generated code. Please see the Programmer's Guide section "Integrating Java and AMF Models" for more on that.</p>
-<p>If you do decide to use the Method Action, keep in mind the following design practice recommendations:</p>
-<div class="orderedlist">
-<ol class="orderedlist" type="1">
-<li class="listitem">
-<p>Keep your usage of external API references to a minimum. If you can use only code provied by the core Java classes as well as the Apache Collections library, your code should work on every current Java target. On the other hand, if you make use of a specific ABM platform APIs your code will obviously only compile and run against that target.</p>
-</li>
-<li class="listitem">
-<p>Code should be in the form of a method body, excluding the signature. A single Java method is created using this code body. There is no support for input parameters -- if you need access to evaluated values from source actions, create agent attributes for them, set their values for the selected agents, and use them as sources for your Method Action.</p>
-</li>
-<li class="listitem">
-<p>All Java class references should be fully qualified. For example, if you wish to use the eclipse Draw2D Graphics class, you should refer to "org.eclipse.draw2d.Graphics", not simply "Graphics". If classes are not fully qualified, you will recieve compile errors. You can usually easily fix these by selecting your source code directory and choosing
- <span class="bold"><strong>Source > Organize Imports..</strong></span> but it prevents automatic code generation.
- </p>
-</li>
-<li class="listitem">
-<p>The method interface has no support for code completion, syntax checking or other common Java development environment features. You can avoid code maintenance and even support targetting multiple APIs by using the following technique. From your method body, call a helper method in a seperate class. The referred class could use a static method call, or you could instantiate the class and call a method against it, passing in the agent class so that the helper class can reference the agent's state. For example, if you wanted to use some custom java code to import agents from a specialized input file, you could put the following code in the Method Action body for the root Context:</p>
-</li>
-</ol>
-</div>
-<div class="literallayout">
-<p>(new org.me.SpecialFileLoader()).load(this);<br>
-
-</p>
-</div>
-<p>Then create a new source directory in your project called "src" (
- <span class="bold"><strong>New > Source Folder...</strong></span>) and create the class for the specialized file loader including the following method:
- </p>
-<div class="literallayout">
-<p>public void load(MyRootModel model) {...}<br>
-
-</p>
-</div>
-<p>This approach allows you to a) maintain the working code using the Java Development Environment, b) avoid changes to the Method Action within the model, and most importantly, c) allow other implementations of the code using multiple APIs. For example, if you need to create a specialized graphics routine, you could create seperate implementations for your Escape (Eclipse Draw 2D), Ascape (Java Swing), and Repast (Simphony API) and place them in the appropriate projects. As long as the different Java source files have the same names and signatures, they will all compile correctly and execute the appropriate behavior.</p>

-</div>
-</div>
-</div>
-<p>Query and Evaluation Actions are both "Sinks" which means that they are capable of containing inputs. When you select a function, the appropriate number of inputs will be created. After selecting a function, you can view and select the inputs. The choices for the inputs will be constrained by the type of the function and the other operands you've selected.</p>

-<div>
-<div>
-<h6 class="title">
-<a name="N1062F"></a>Input Literals</h6>
-</div>
-</div>
-</div>
-<p>Inputs can take literal values; that is values that you specify simply by entering them directly into the query. In general it is useful to think of literals as similar to local variables in a conventional programming language, whereas attributes are analogous to member variables. (And this is how they are represented in the generated Java code.) As with local variables in model code, literals are not recommended for any values that can change model behavior. The value cannot be easily accessed or changed by other model users. For greater transparency, you should instead create an Attribute with an appropriate default value, setting the "immutable" value to true. Still, literals can be useful for values that are special cases related to the evaluation or query, such as an input code, and for quickly prototyping functionality.</p>

-<a name="Example"></a>Example</h3>
-</div>
-</div>
-</div>
-<p>In this section, we'll look at an example that should make clear how the basic Actions approach works in a model. Say we want to define a behavior like:</p>
-<div class="literallayout">
-<p>"Search for a random agent within my vision that is the same age as I am. Find a location next to that agent that is not already occupied and move to it."<br>
-
-</p>
-</div>
-<p>Here, we create a sequence of actions like so:</p>
-<div class="orderedlist">
-<ol class="orderedlist" type="1">
-<li class="listitem">
-<p>Select every agent for every period of the model. ("Find Partner" Rule)</p>
-</li>
-<li class="listitem">
-<p>For every member of that selection, search for other agents of the same age within vision distance. ("Partner" selection.)</p>
-</li>
-<li class="listitem">
-<p>From "Partners" find a random member and search for a neighboring locations. ("Partner Neighbor" selection.)</p>
-</li>
-<li class="listitem">
-<p>Finally, move the agent in "Find Partner" to the "Partner Neighbor" location.</p>
-</li>
-</ol>
-</div>
-<p>Now, notice that although it's convenient to speak as if there is only one "Find Partner" and one "Partner Neighbor" in step 4 above, in fact selections are flowing through for each of the results of each of the previous action sequences, and we can refer to each of the directly. We could represent these behaviors in many different ways. For example, we might want to specify the model in a (hand-drawn) graphical language or in a (made-up) textual language:</p>
-<p>
-
-</p>
-<div class="mediaobject">
-<img src="images/actions/ActionsExample.png"></div>
-<p>
-
-</p>
-<p>This is how it looks in an actual model:</p>
-<p>
-
-</p>
-<div class="mediaobject">
-<img src="images/actions/ActionsExampleNew.png"></div>
-<p>
-
-</p>
-<p>And here is how this works in detail:</p>
-<div class="orderedlist">
-<ol class="orderedlist" type="1">
-<li class="listitem">
-<p>Create a Rule that will trigger the behavior. In this case, we want this rule to apply to all "Individual" agents within the model. (Space isn't relevant in this case.</p>
-</li>
-<li class="listitem">
-<p>Create a child Select Action that will find our partner. Two important things to note here:</p>
-<div class="orderedlist">
-<ol class="orderedlist" type="a">
-<li class="listitem">
-<p>The selection occurs based on the "Find Partner" selection. This means that for each Individual in the model, we'll be searching from the point of view of that agent to some other selection of agents.</p>
-</li>
-<li class="listitem">
-<p>We also need to define what type of agent we want and in this case the space does matter. We want to find an agent that is nearby within the City space. If instead we wanted to find a partner in a social network, we'd specify that instead.</p>
-</li>
-</ol>
-</div>
-</li>
-<li class="listitem">
-<p>Create two child Query Actions:</p>
-<div class="orderedlist">
-<ol class="orderedlist" type="a">
-<li class="listitem">
-<p>We want to search for someone who is the same age as us. This highlights the importance of the idea of the Selection in the Actions design. We're qualifying Age by the rule agent's partner for the first input and by the rule agent for the second. The selection carries throughout the flow of execution and this context is an explicit part of the entire structure. Note that this is very different from the way control flow works in a traditional imperative language such as Java.</p>
-</li>
-<li class="listitem">
-<p>We also want to search using a function for nearness, "within", which takes a parameter of vision. Note that the spatial functions are all polymorphic -- if we decided later on that we would rather search within say "Kevin Bacon space", that is a graph structure representation of space, we would only need to change the space we've defined in Select Partner.</p>
-</li>
-</ol>
-</div>
-</li>
-<li class="listitem">
-<p>Intersect the results of these two query components. This delineates the end of the selection definition for any target Actions.</p>
-</li>
-<li class="listitem">
-<p>Select a neighbor. Again, we can see the importance of Selections. Here, we are selecting from the point of view of the partner, not the initial agent that the current Rule is being executed for. Note that this time our target agent is a "Block", that is, a location within the city.</p>
-</li>
-<li class="listitem">
-<p>As above, define some queries. This time we want only those agents that are:</p>
-<div class="orderedlist">
-<ol class="orderedlist" type="a">
-<li class="listitem">
-<p>available, and</p>
-</li>
-<li class="listitem">
-<p>neighbors of our partner.</p>
-</li>
-</ol>
-</div>
-</li>
-<li class="listitem">
-<p>And another intersection..</p>
-</li>
-<li class="listitem">
-<p>Finally, we move to the location we've found. All that's required at this point is to specify:</p>
-<div class="orderedlist">
-<ol class="orderedlist" type="a">
-<li class="listitem">
-<p>The movement selection, or those agents that are moving, which in this case is the original agent we're executing the rule for, and</p>
-</li>
-<li class="listitem">
-<p>The destination, which is the cell that we've found. Note that the framework infers from the space definition that the Block agent is capable of hosting the Individual.</p>

-<p>All Actions have as their root-most source action a Root. These are added first to any agent behavior and act as triggers for all target behavior. For example, a Watch will execute any time the watched attribute is modified. (As the diagrams do not refer to elements outside of the current package, we cannot see here that Accessor includes a reference to some Attribute, but it does. To see these kinds of relationships you will want to refer to the metaabm.ecore file itself.)#Actions are targets and sources of one another, but an Act can never have itself as a source.

When we refer to an Act source or target, we typically mean to include all ancestors or descendants, not just the immediately connected Act.)</p>

-<li class="listitem">
-<p>All Actions (except for root Actions) reference a Select, referred to as the "selected" relation. An ASelect represents the model aspects that the Act is working within; that is, the spatial, temporal and type (agent) "world" that is currently being selected.</p>

-<p>Functions are relatively simple in terms of model design, but we need to understand how particular functions work in order to develop models. Functions are divided in two ways. By type:</p>
-<div class="orderedlist">
-<ol class="orderedlist" type="1">
-<li class="listitem">
-<p>Operators are simple calculations sharing the same type.</p>
-</li>
-<li class="listitem">
-<p>Functions that can represent any general function that takes some well-defined input(s) and returns some well-defined output(s).</p>
-</li>
-</ol>
-</div>
-<p>And by usage:</p>
-<div class="orderedlist">
-<ol class="orderedlist" type="1">
-<li class="listitem">
-<p>Generics can return any value and are used in Evaluate actions.</p>
-</li>
-<li class="listitem">
-<p>Logicals return some boolean result and are used by Query actions to decide whether target Actions apply to a particular selection, and by Evaluate actions just as with any other functions. Input types should be defined as generally as possible.</p>
-</li>
-</ol>
-</div>
-<p>These overlap, so we have operators, logical operators, functions and logical functions. Functions are also divided into categories. We'll go through each of these in depth below.</p>
-<p>The most important thing to point out about functions is that - as we've seen with other Acore concepts -- they provide richer sets of functionality than traditional approaches. Many functions are designed to collaborate with one another as we'll see when looking at Spatial and Graphical functions. Functions can also trigger the creation of related model artifacts as we'll see with the Distribution functions.</p>
-<p>A technical note: conceptually, functions can return multi-values, but that is not currently implemented in the reference targets because of limitations of the target language Java.</p>

-<p>Spatial functions provide the core functionality for Agent Models. Spatial functions are polymorphic, which basically means that they don't care what space they are operating on as long as that space is suitable for them. Spatial functions are designed to collaborate with one another. For example, by intersecting the "Neighbor", "Available" and "Toward" functions, we can design a rule that causes the agent to move to the next neighboring cell that get's it closer to some target agent. See the function details for more information.</p>

-<p>Graphic functions are combined within Style Evaluate Actions to determine how to draw an agent within a visualization. One nice aspect of this approach is that the same style definition can be used in multiple places without changing any code. For example, the same style could be used to draw an agent on a two-dimensional grid within Escape, a three-dimensional shape within Escape, a Java Swing based visualization in Ascape, and an XML configured visualizaiton in Repast Simphony.</p>
-<p>To define a graphic style for an agent, design a flow in which you create Evaluate Actions for color and shape, and then create an Evaluate Action with the graphic fill or outline function as a target of these.</p>

-<p>Escape is a full-featured Agent-Based Modeling (ABM) integrated development environment (IDE) with a Java based API and end user modeling tools. It's based on Ascape, which has been in use for more than 10 years. The core API is very stable, and that should give users a way to explore the features of AMP without concerns about keeping in synch with the rapidly evolving AXF /AGF API. It allows modelers to code in Java and/or generate models with AMF and then execute those models within the same development environment.</p>
-<p>
-
-</p>
-<div class="mediaobject">
-<img src="images/EscapeExecutionScreenshot.png"></div>
-<p>
-
-</p>
-<p>A primary purpose of the Escape project -- apart from the obvious goal of providing a nice Eclipse hosted ABM toolkit -- is to provide an exemplar to demonstrate how any arbitrary agent modeling framework can be integrated within the AMP environment. A cool aspect of this is that AMP has no dependencies on Escape, but also that the underlying ABM modeling framework for Escape has no dependencies on AMP -- instead Escape simply provides the runtime glue between AMP and the ABM framework. The underlying ABM framework uses the Ascape API, an API that first began development more than ten years ago and that has not been modified at all in order for it to work within the AMP environment.</p>

-<p>Because it's API is based on Ascape, Escape is one component of AMP that already has extensive documentation. There is complete Javadoc as well as a manual and other web resources. See the
- <a class="ulink" href="http://ascape.sourceforge.net" target="_new">Ascape Website</a> to locate these resources. There is a
- <a class="ulink" href="http://ascape.sourceforge.net/docs/TheAscapeManual5.pdf" target="_new">full manual</a> for Ascape available on that site. Or, you can install the Ascape Manual into the eclipse help system by adding the following update site and selecting the "Documentations and Source Code" feature.

-<p>Escape is

If you want to do 3D (really 2 1/2) visualizations, you will want AGF3D and the LWJGL dependency. You can build from source but in that case you'l need to launch a self-hosted runtime, so it's best to simply install from the update site if you're not actually doing AMP development.

-</div>
-</div>
-<p>The easiest way for Java developers to get started doing agent-based modeling in Eclipse is to begin to write programs using it. To develop new models, you can:</p>
-<div class="orderedlist">
-<ol class="orderedlist" type="1">
-<li class="listitem">
-<p>Create a new Escape project. The Escape projects are actually configured for AMF code generation so there are dependencies and builders in there that you don't need; you can remove all of the escape builders and any of the kitchen sink items. The "Create an Escape Java Model" cheat sheet will walk you through the process of creating a new Java based project and model.</p>
-</li>
-<li class="listitem">
-<p>Or for more experienced Eclipse users, you can simply to just create a new Plugin Project and add the necessary dependencies there. Have a look at the example escape project to see what you need. Note that you will likely need more dependencies then you need to simply build -- this is because the class loader uses the classes from the project path and so runtime classes have to be there as well. We may simply package an Eclipse runtime convenience plugin to gather these dependencies up a bit.</p>
-</li>
-</ol>
-</div>
-<p>Then just create new Java classes for your root model scape and agents just as you would for an Ascape project.</p>

-<p>If you're like many Java developers, you might find point-and-click interfaces a bit lame. Personally, I've changed my tune in this, and I now define all of my ABM models from the editor, saving Java for truly specialized tasks. But even without generation of agent behavior, Acore can be a really valuable tool, as the GIS example shows. The way to look at metaABM is as a way to compose your overall model and automate the tedious parts. Apart from Java generated code, the AMF meta-model maintains a number of very useful artifacts. For example, the Repast Simphony target maintains model.score and all of the model.rs component. Generally, AMF should save time and hassle while making your models far more transparent even if you never use the Actions component to define agent behavior.</p>
-<div class="section" title="Method Action">
-<div class="titlepage">
-<div>
-<div>
-<h4 class="title">
-<a name="Method_Action"></a>Method Action</h4>
-</div>
-</div>
-</div>
-<p>As explained in the action section, you can simply create a "Method" act with hand-written Java code. This option is nice because all code is contained within the AMF file. But it can be difficult to maintain large blocks of Java code as you aren't using a Java editor to edit the Java code itself. One way to get around this is to create your code in the generated Java method and then copy it into the Method action. Note one imporant issue here -- you'll generally have to fully qualify your Java references as you won't be able to change the imports statements directly. </p>

-<div class="section" title="Protected Code Regions">
-<div class="titlepage">
-<div>
-<div>
-<h4 class="title">
-<a name="Protected_Code_Regions"></a>Protected Code Regions</h4>
-</div>
-</div>
-</div>
-<p>You can mix and match Action behavior with Java and generated code with POJOs. One way to do this is through using protected regions. Select the agent you want to create protected methods for and then select "Generate Protected" from the "Mode" property. Now, create actions just as you have before, or use your existing ones. On code generation, open up the relevant java file and examine the methods that have been created. </p>
-<p>
-
-</p>
-<div class="mediaobject">
-<img src="images/pojo/ProgrammingPojoGenerateProps.png"></div>
-<p>
-
-</p>
-<p>You can put whatever you want within the PROTECTED REGION comments and those changes will be preserved when the model is regenerated. You can create a schedule, rule or watcher, maintain custom code for the actual implementations, and still have the model adapt to changes in the underlying data structure -- if for example you want to import a modified shape file.</p>

-</div>
-</div>
-</div>
-<p>Another approach which can be more robust is to generate the basic model stubs (like an abstract base class except that it isn't abstract) and then override your model with implementations. AMF provides support for generic skeletons and interfaces.</p>

-</div>
-<p>Because Escape uses SWT and Ascape uses Swing, there are a few unavoidable incompatibilities. Most of these we avoid by using higher level APIs but here are the key changes that you're likely to have to make:</p>
-<div class="section" title="Convert the low-level imports from AWT and Swing to SWT">
-<div class="titlepage">
-<div>
-<div>
-<h5 class="title">
-<a name="Convert_the_low-level_imports_from_AWT_and_Swing_to_SWT"></a>Convert the low-level imports from AWT and Swing to SWT</h5>
-</div>
-</div>
-</div>
-<p>The simplest way to accomplish this is to remove all of the imports and then organize imports. For example:</p>
-<div class="literallayout">
-<p>java.awt.Color => org.eclipse.swt.graphics.Color<br>
-java.awt.Graphics => org.eclipse.draw2d.Graphics<br>
-
-</p>
-</div>
-<p>Then just do a global find for all of the imports and replace them with nothing. This is a great place for a regexp. Try:</p>
-<div class="literallayout">
-<p>find: import java\.awt\.(.*);<br>
-replace: [nothing]<br>
-
-</p>
-</div>
-<p>You don't have to replace these with the SWT equivalents, just click on the project, right-click and choose "Source:Organize Imports.."
- By the way, a great way to avoid having to select the right entries in optimize imports and to alert you when you have missed anything is to prevent the awt and swing classes from being used at all. Right-click on project, choose "Build Path:Configure Build Path", go to Libraries tab, open JRE System Library, choose "Access Rules", edit, and then add entries for java/awt/** and javax/swing/**. The code will regenerate and you'll have error markers for all of the stuff that won't work with Escape and Eclipse.</p>
-</div>
-<div class="section" title="Convert color features">
-<div class="titlepage">
-<div>
-<div>
-<h5 class="title">
-<a name="Convert_color_features"></a>Convert color features</h5>
-</div>
-</div>
-</div>
-<p>You can't use AWT colors either so you'll need to replace any colors. AMP provides a convenience classes for Colors called ColorFeature and ColorFeatureConcrete. You can use these or any of the other ways to define SWT colors. For example:</p>
-<div class="literallayout">
-<p>Color.lightGray => ColorFeature.LIGHT_GRAY<br>
-new Color(Math.min(1.0f, (float) (redEnergy + orangeEnergy)), (float) orangeEnergy * .8f, (float) blueEnergy) => <br>
- ColorFeatureConcrete.create(Math.min(1.0f, (float) (redEnergy + orangeEnergy)), (float) orangeEnergy * .8f, (float) blueEnergy)<br>
-
-</p>
-</div>
-</div>
-<div class="section" title="Change agent color getters">
-<div class="titlepage">
-<div>
-<div>
-<h5 class="title">
-<a name="Change_agent_color_getters"></a>Change agent color getters</h5>
-</div>
-</div>
-</div>
-<p>If you've defined colors through overriding Agents as in most models, you'll need to change the method signature. You could just do a global replace for this one.</p>
-<div class="literallayout">
-<p>public Color getColor( => public Object getPlatformColor(<br>
-
-</p>
-</div>
-</div>
-<div class="section" title="Get rid of image features">
-<div class="titlepage">
-<div>
-<div>
-<h5 class="title">
-<a name="Get_rid_of_image_features"></a>Get rid of image features</h5>
-</div>
-</div>
-</div>
-<p>Escape doesn't support them. In practice they haven't been used a lot. At some point perhaps we'll have nice sprite support instead. :)</p>
-<div class="literallayout">
-<p>public Image getImage() {**} => ""<br>

-<div class="section" title="Modify usages of DrawFeatures">

-<div>
-<div>
-<h5 class="title">
-<a name="Modify_usages_of_DrawFeatures"></a>Modify usages of DrawFeatures</h5>
-</div>
-</div>
-</div>
-<p>If you've created any of your own draw features, you'll need to change them slightly to accommodate the differences between the AWT and SWT / Draw2D APIs. This should be pretty straightforwrd. For example:</p>
-<div class="literallayout">
-<p>g.setColor(...<br>
-g.fillOval(..<br>
-becomes:<br>
-g.setBackgroundColor(<br>
-g.fillOval(..<br>
-
-</p>
-</div>
-<p>That's about it, though it's probable that we've missed something. Please post a message on the amp newsgroup if you run into any other conversion issues.</p>

-</div>
-</div>
-</div>
-<p>Instead of using Ant, Escape has really nice support for parameterizing and testing models. See
- <a class="ulink" href="/wiki/Experimenting_and_Testing" target="_new">Experimenting and Testing</a> (todo). If you do want to work with ant you will need to install the plugins from the Sourceforge download site. (These have dependencies that I didn't want to bother with going through the Eclipse IP process to get in. If for some reason you think these should be part of core Escape let Miles know and I'll take care of it.) Ant has not been tested for Escape so it's not even clear it will work.

-<p>Many models have been created using Ascape over the years, including all of the classic models created at Brookings and some other cool models such as Craig Reynold's Boids and a pretty cool little traffic model, and they've all been converted to run in Escape. They're in Java but you can execute and explore them in exactly the same way as the Epidemic model above. All of the Ascape example models have been converted (a straightforward process) from their intial Ascape incarnations. For licensing reasons (they're BSD, not EPL) we can't host them directly on the Eclipse site. You can get the projects in two ways:</p>
-<p>Once you've downloaded the projects, open up the src folder and navigate to the Java files for the actual models. For example, to run Conway's Life, you'll want src/edu.brook.life.ConwayLife. Right-click on the Java file and select "Execute". There are many models to explore! (It's not always obvious which Java files are for models, so you may have to poke around a bit. We need to put together a catalog here. Another nice opportunity for user contributions.)</p>
