Figure 1. Cultural Geography Model<br />

The Cultural Geography (CG) model, shown in Figure 1, is a<br />

government owned, open source prototype agent-based<br />

model of civilian populations currently implemented in Java<br />

and using Simkit as the simulation engine.<br />

The model aims, through the implementation of social<br />

and behavioral science, to track individual, group-level and<br />

population-wide changes on positions related to various<br />

issues.<br />

At its current stage the model examines the issues of<br />

security, elections and infrastructure.<br />

Goals<br />

We had the following goals <strong>for</strong> IDFW 20:<br />

• Create an agent prototype that decides on its actions<br />

using utility theory.<br />

• Create code to support the utility agent’s decision<br />

process.<br />

• Test the utility agent’s functionality within the CG<br />

model.<br />

• Design an experiment using <strong>Data</strong> <strong>Farming</strong> techniques<br />

<strong>for</strong> evaluating the utility agent’s per<strong>for</strong>mance<br />

Analysis<br />

Our methodology include the development of an Agent<br />

Template <strong>for</strong> implementation, improvement and finalization<br />

of the template, development of an experimental design, and<br />

comparative analysis with different utility functions and<br />

roles.<br />

The principle of maximum expected utility (MEU) says<br />

that a rational agent should choose an action that maximizes<br />

the agent’s expected utility. For the purposes of this project,<br />

we consider as utility the change in the population’s stance<br />

on the issue of Security.<br />

To determine the utility of an action we tracked the<br />

execution of each action, track the utility accumulated<br />

following each rule firing, discounted the utility to determine<br />

the present value of the utility at the time of execution, and<br />

determined the mean utility received <strong>for</strong> each rule fired at the<br />

time of firing. We then selected action based on the activation<br />

level and the Boltzmann distribution. Our initial violent<br />

extremest network consisted of 30 insurgents across 10 zones.<br />

Future Work<br />

Our plans <strong>for</strong> future work include incorporating additional<br />

attributes into the utility function, developing additional<br />

roles within the insurgent network, and exploring the use of<br />

different utility functions <strong>for</strong> different roles within the<br />

network.<br />
