There is a common belief that humans and many animals follow transitive inference (choosing A over C on the basis of knowing that A is better than B and B is better than C). Transitivity seems to be the essence of rational choice. We present a theoretical model of a repeated game in which the...

Previous models of collective action assume that the network structure of individual relations that transmit social control mechanisms promoting or inhibiting collective action is given. An extended game-theoretical model that incorporates social control mechanisms as side payments and allows...

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 …

In this paper, we study an aspiration-induced migration model, in which each individual plays the prisoner’s dilemma game with those being within a circle of radius r centered on himself/herself. An individual will migrate to a randomly chosen place with the velocity v if his/her payoff is...

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 …

Critical social ensembles are generated using a decision making model (DMM) consisting of a master equation, with two-state elements at the nodes of a two-dimensional lattice. The dynamics of the DMM undergo phase transitions to either a consensus state or another state composed of apparently...

Cooperation in prisoner’s dilemma game can be promoted significantly by introducing memory effects. In this work, we … numerically investigated robustness of cooperation by introducing an attack probability, with which an individual in cooperation … vanishment of the cooperators. Our work could be helpful to understand the emergence of cooperation in systems consisting of …
