"The prisoner's dilemma has historically been used in international relations studies to model interactions between states. In this paper, we implement several iterated prisoner's dilemma models across a GIS-derived network of state-level agents and simulate local interactions between bordering states. Our first model (Model 1) studies the evolution of regional behavioral norms; the second (Model 2) investigates bilateral interactions driven by competition for regional hegemony."
"Model 1: each state has a single behavior: it either cooperates or defects with all of its neighbors":
"Model 2 allows states to adopt a different behavior with regard to each other state; instead of a single action, each state has a table of actions, one per neighbor":
