Cooperation in networks of mobile agents
All species possess the instinct of seeking favorable living environments but abandoning the adverse ones, which is usually achieved by way of migration. We constructed a model to study how the migration a ects the emergence and evolution of cooperation in the context of the prisoner’s dilemma game, an issue central to our understanding of biological systems and human societies. Specifically, dissatisfied players, who have been exploited by defectors, tend to leave the current habitats, and explore unknown physical niches. These niches can stand for resources, shelters, and so forth. Cooperation can build up for a wide range of model parameters in which cooperation is always doomed in the absence of migration. Intriguingly, three possibilities of cooperators dominance, coexistence, and defectors dominance can emerge depending on how fast natural selection happens relatively to interaction. Thus the time scale ratio of natural selection to interaction is naturally married with the migration mechanism, and has very vital role in determining the evolutionary fate of cooperators. We hope that the results reported here can shed light on further understanding the emergence of cooperation in adaptive populations.
