We study an evolutionary spatial prisoner's dilemma game where the fitness of the players is determined by both the payoffs from the current interaction and their history. We consider the situation where the selection time scale is slower than the interaction time scale. This is done by implementing probabilistic reproduction on an individual level. We observe that both too fast and too slow reproduction rates hamper the emergence of cooperation. In other words, there exists an intermediate…

Evolution of Interactions and Cooperation in the Spatial Prisoner's Dilemma Game
The findings reveal that the “making of new friends” may be an important activity for the successful evolution of cooperation, but also that partners must be selected carefully and their number limited.
Emergence of cooperation through coevolving time scale in spatial prisoner's dilemma.
It is found that the greater the losers increase their strategy-selection time scales, the better for cooperation.
Repeated thinking promotes cooperation in spatial prisoner's dilemma game
Inspired by the realistic process of taking decisions in social life, we have proposed a repeated thinking mechanism in the evolutionary spatial prisoner's dilemma game where players are denoted by
Stochastic Heterogeneous Interaction Promotes Cooperation in Spatial Prisoner's Dilemma Game
Simulations on a 4-neighbor square lattice and BA scale-free network results indicate that the stochastic heterogeneous interaction can be robust against different network topologies and may sharpen the understanding of the joint effect of game time-scale and individual diversity on spatial games.
Cooperation and age structure in spatial games.
The demographic heterogeneous age distribution, directly affecting the outcome of the game, is shown to be responsible for enhancing the cooperative behavior in the population and moderate values of α allow cooperators not only to survive but to outcompete defectors.


Selection of dynamical rules in spatial Prisoner's Dilemma games
We study co-evolutionary Prisoner's Dilemma games where each player can imitate both the strategy and imitation rule from a randomly chosen neighbor with a probability dependent on the payoff
Time scales in evolutionary dynamics.
It is shown that eliminating this restriction by explicitly considering the time scales of interaction and selection leads to dramatic changes in the outcome of evolution.
Interaction stochasticity supports cooperation in spatial Prisoner's dilemma.
Simulation results show that there exists an optimal region of the intensity of interaction resulting in a maximum cooperation level, and good agreement between simulation results and theoretical predictions obtained from an extended pair-approximation method is found.
Cooperation enhanced by inhomogeneous activity of teaching for evolutionary Prisoner's Dilemma games
The results highlight the importance of asymmetry characterizing the exchange of master-follower role during the strategy adoptions in evolutionary Prisoner's Dilemma games with quenched inhomogeneities in the spatial dynamical rules.
Coherence resonance in a spatial prisoner's dilemma game
We study effects of additive spatiotemporal random variations, introduced to the payoffs of a spatial prisoner's dilemma game, on the evolution of cooperation. In the absence of explicit payoff
Making new connections towards cooperation in the prisoner's dilemma game
It is shown that there exist an optimal maximal degree for the promotion of cooperation, warranting the best exchange of information between influential players and results in highly heterogeneous interaction networks with an exponential fit best characterizing their degree distributions.
Phase diagrams for an evolutionary prisoner's dilemma game on two-dimensional lattices.
Using Monte Carlo simulations and the generalized mean-field approximations, the phase boundaries (critical points) are determined separating the two phases on the plane of the temperature (noise) and temptation to choose defection.
Spatial structure often inhibits the evolution of cooperation in the snowdrift game
The results caution against the common belief that spatial structure is necessarily beneficial for cooperative behaviour, and show that no such general predictions can be made for the effects of spatial structure in the snowdrift game.
Randomness enhances cooperation: a resonance-type phenomenon in evolutionary games.
Simulation results show there is an optimal amount of randomness, which can induce the highest level of cooperation, and in such randomness' presence, the system evolves more frequently to a cooperative state than in its absence.
Evolutionary game theory can be extended to include spatial dimensions. The individual players are placed in a two-dimensional spatial array. In each round every individual “plays the game” with its
