Ascape is a software framework for developing and analyzing agent-based models. In Ascape, agent objects exist within scapes; collections of agents such as arrays and lattices. These scapes are themselves agents, so that typical Ascape models are made up of “collections of collections” of agents. Scapes provide a context for agent interaction and sets of rules that govern agent behavior. Ascape manages graphical views and collection of statistics for scapes and provides mechanisms for controlling and altering parameters for scape models.
