In order to get reliable results from agent-based models, simulations typically have to be run many times and results averaged, given that while the rules determining agent behavior in a model may be fixed, they often involve random processes e.g., movement in a random direction. The first step towards model reduction involves figuring out how many simulations must be run for fixed parameter settings in order to obtain reliable results this value may be model dependent. We are interested in automatic conversion of agent-based models to systems of equations. We are currently working on parameter estimation methods that show some promise. In this approach, we generate data from the simulation and attempt to determine parameters that fit the equations to the data. This work has been successful with the Rabbits and Grass model and is currently underway for a more spatially complicated version of SugarScape.
