Simulations of complex systems models provide a numerical laboratory for studying emergent spatial phenomena. We report on simulations of the 2-dimensional spatial prisoners' dilemma with both 4- and 8-neighbour playoffs. We identify non-monotonic dependence of the convergent population of defectors with the variation of defection temptation reward in the 8-neighbour system. We present some microscopic configuration analyses to explain this phase transitional effect.
Keywords: prisoner dilemma; game theory; agent population dynamics; simulation.
