In between Schelling and Maynard-Smith

Hugues Bersini

Abstract (Excerpt)

In the history of agent-based/Alife simulations helping to better understand some unexpected social consequences emerging out of interactive individual behaviors, two models have become quite celebrated: the Schelling's segregation model and the Maynard-Smith's emergence of cooperation in an albeit very defective world. In this paper, we explore a simulation at the crossroad of these two models. We show how in a bi-color society in which individual can move according to their neighborhood "colored" composition (reminiscent of the original Schelling's model), one further way to favor cooperation is to encourage "communitarian" behavior i.e. allowing individual to move, compose clusters of similar color and evolve a cooperative behavior restricted to partners of the same color. In brief, our results not so surprisingly tend to show that communitarian cooperation and segregation evolve hand in hand.
