By means of a two-dimensional cellular automaton we investigate an iterated Prisoner’s Dilemma (IPD) game with 8 different strategies and one-step memory. Spatially distributed agents are assumed to interact in a local neighborhood and to adopt the strategy of their most successful neighbors after each generation, this way increasing their individual payoff. Particular emphasis is on the temporal change of the spatial distribution of the different strategies and their global frequencies. In order to get a better insight into the dynamics, we further vary the stochasticity, the size of the local neighborhood and the number of interactions per generation.
