Network Adaptation Based On Environment Feedback Promotes Cooperation In Co-evolutionary Games

In the evolutionary game model,the choices of individuals will form the system environment,and the environment will in turn affect the individuals’choices of strategy.At the same time,individuals in adaptive social structures are able to promote group cooperation by timely switching their interacting neighbors.Here,we propose a co-evolutionary game model based on the prisoner’s dilemma,in which the network structure adaptively updates as the cooperative environment changes while the individual strategy evolves.By controlling parameters,we can adjust the time scale between the strategy evolution and the network adaptation in the evolutionary game model.The results show that network adaption based on environmental feedback can significantly improve the cooperation level,and the rapid evolution of network structure is conducive to improving the level of cooperation.By examining individual local cooperative environments,reconnecting individual proportions,and the time scale of co-evolution,we provide a new perspective for the study of co-evolutionary game models.
