We introduce the vertex weight into the spatial prisoners’ dilemma game to investigate the evolution of cooperation … the exponential, power-law and uniform ones. Compared with the traditional version, we find that the cooperation level is … markedly enhanced under the weighted square lattice. For most ranges of b, the highest cooperation level can be obtained under …

A fundamental question of human society is the evolution of cooperation. Many previous studies explored this question ….e., integrating neighborhoods in the evaluation of fitness, promotes cooperation. If we enhance the value of u, the invasion of … influence of the environment on the evolution of cooperation. Finally, the universality of this mechanism is testified for …

the multiplication factor. We attribute the enhancement of cooperation to the inherited fitness that stabilizes the …

results show that moderate values of elimination threshold can result in a maximum cooperation level in the evolutionary … degree distribution, which is considered to be helpful in promoting cooperation in evolutionary games. The present study may … provide new insight for understanding the evolution of cooperation in light of the law ‘survival of the fittest’ in nature. …

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 …

The basic difficulty in cooperation theory is to justify the cooperation. Here we propose a new approach, where players … are driven by their altruism to cooperate or not. The probability of cooperation depends also on the co …-player’s reputation. We find that players with positive altruism cooperate and meet cooperation. In this approach, payoffs are not …
