Evolution of mobile strategies in social dilemma games: An analysis of cooperative cluster formation

This paper analyses the formation of cooperative clusters toward the emergence of cooperative clusters in evolutionary spatial game theory. In the model considered, agents inhabit a toroidal lattice grid, in which they participate in a social dilemma games, and have the ability to move in response to environmental stimuli. In particular, using the classical 2-player prisoner’s dilemma and a generalised N-player prisoner’s dilemma, we compare and contrast the evolved movement strategies, and the cooperative clusters formed therein. Additionally, we explore the effect of varying agent density on the evolution of cooperation, cluster formation, and the movement strategies that are evolved for both cooperative and non-cooperative strategies.
