Repast

Repast is a library for agent-based simulation models, involving Java programming. It allows a great flexibility in developing social interaction models for non-representative agents.

   Examples from Repast website

Friendship Network
This is an implementation of the second model (model II) described in Jin, Girvan, and Newman, "The Structure of Growing Social Networks." Santa Fe Institute 2001 working paper. Click here to download the paper.

SugarScape
An partial implementation of the Sugar Scape simulation from "Growing Artificial Societies" by Epstein, Joshua M and Axtell, Robert. This implements rules G, R, and M from chapter II. Click here for more information about this model.
