The agent-based simulation used by the Village Ecodynamics Project is called "Village" and consists of about 17,000 lines of Objective-C code written for the Swarm simulation platform. This chapter provides an overview of the structure, schedule, main agent actions (methods), and key parameters in the simulation. We show that growth rates exhibited by the agents in the simulation are realistic for Neolithic populations, and that variability in numbers of agents through time introduced by using different random number seeds is relatively small.
