A fundamental question of human society is the evolution of cooperation. Many previous studies explored this question … undoubted fact is that the environment plays an important role in the individual development. Inspired by these phenomena, we ….e., integrating neighborhoods in the evaluation of fitness, promotes cooperation. If we enhance the value of u, the invasion of …

evolution of cooperation and the wealth distribution under different updating rules are investigated. Numerical results show … that the cooperation is highly promoted when the hub nodes are favored in the payoff matrix, which seems to harm the … the node difference is eliminated in the learning strategy, the asymmetric payoff rule will not affect the cooperation …
