囚徒困境博弈策略在社团网络中的演化
Evolution of prisoner’s dilemma strategies on community network

为深入探讨社团网络的网络拓扑结构如何影响合作的演化和维持，在社团网络框架下，进行重复囚徒困境博弈. 模拟结果表明了社团强度Q明显影响了群体的合作情况，具有适当社团强度的网络，可以促进合作的形成，且具有较高聚类系数的网络能激励合作行为的演化. 当网络平均度越大，越无益于合作行为的产生.
In order to further investigate how the topological structure affects the evolution and maintenance of cooperation，in this paper the repeated game about prisoner’s dilemma is going under the framework of community network. The simulation results show that the community strength significantly influences the evolution of cooperation between groups；the cooperation level can be highly enhanced with appropriate community strength. Community network has a high clustering coefficient can motivate cooperative behavior. Simultaneously indicating，it is not conducive to promoting cooperation when the network average degree greaten
