This paper describes the use of genetic algorithm based approaches to explore the evolution of cooperative behavior in N player generalizations of prisoner's dilemma. In these experiments, quasi-stable cooperation emerges for coalitions of cooperators of all sizes greater than a minimum coalition size determined by the payoff structure of the game. The framework described here produces emergent cooperation reproducibly as long as minimum coalitions are 3 or less. For games with large minimum coalition sizes, cooperative behavior is not observed.
