Reputation and reciprocity are key mechanisms for cooperation in human societies, often
going hand in hand to favor prosocial behavior over selfish actions. Here we review recent …

Why would natural selection favor the prevalence of cooperation within the groups of selfish
individuals? A fruitful framework to address this question is evolutionary game theory, the …

Prevalence of cooperation within groups of selfish individuals is puzzling in that it contradicts
with the basic premise of natural selection. Favoring players with higher fitness, the latter is …

We investigate the cooperation dynamics attributed to the interplay between the evolution of
individual strategies and evolution of individual partnerships. We focus on the effect of …

Based on learning theory, we adopt a stochastic learning updating rule to investigate the
evolution of cooperation in the Prisoner's Dilemma game on Newman-Watts small-world …

Uncertainties are ubiquitous in everyday life, and it is thus important to explore their effects
on the evolution of cooperation. In this paper, the prisoner's dilemma game with …

Many recent studies have used reinforcement learning methods to investigate the behavior
of agents in evolutionary games. Q-learning, in particular, has become a mainstream …

Evolutionary games are studied where the teaching activity of players can evolve in time.
Initially all players following either the cooperative or defecting strategy are distributed on a …

We investigate how the degree-mixing pattern affects the emergence of cooperation in the
networked prisoner's dilemma game. Our study shows that when a network becomes …

We study the evolution of cooperation modeled as symmetric 2× 2 games in a population
whose structure is split into an interaction graph defining who plays with whom and a …
