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 />
