Evolutionary game theory in structured populations

​

How can cooperative acts evolve among populations of selfish individuals? In this scenario each simulation agent is an individual who interacts with others playing a repeated game, e.g. the Prisoner's Dilemma (PD) or the Public Goods Game (PGG). Using numerical simulations, we measure cooperation levels when the system evolves according to different strategy update rules. We also study how network topologies such as random graphs, social network models, scale-free networks or spatial networks can influence the system dynamics. This game-theoretical framework approximates many socio-economic scenarios that we daily experience when cooperative norms and conventions spread throughout our society. The results of this research line can then be tested in controlled behavioral experiments with human participants.
