Evolution of interactions and cooperation in the spatial prisoner's dilemma game
Chunyan Zhang, Jianlei Zhang, Guangming Xie +2
We study the evolution of cooperation in the spatial prisoner's dilemma game where players are allowed to establish new interactions with others. By employing a simple coevolutiona…
Resolution of the stochastic strategy spatial prisoner's dilemma by means of particle swarm optimization
Jianlei Zhang, Chunyan Zhang, Tianguang Chu +1
We study the evolution of cooperation among selfish individuals in the stochastic strategy spatial prisoner's dilemma game. We equip players with the particle swarm optimization te…
Does strong heterogeneity promote cooperation by group interactions?
Matjaz Perc
Previous research has highlighted the importance of strong heterogeneity for the successful evolution of cooperation in games governed by pairwise interactions. Here we determine t…
Group-size effects on the evolution of cooperation in the spatial public goods game
Attila Szolnoki, Matjaz Perc
We study the evolution of cooperation in public goods games on the square lattice, focusing on the effects that are brought about by different sizes of groups where individuals col…
Success-driven distribution of public goods promotes cooperation but preserves defection
Matjaz Perc
Established already in the Biblical times, the Matthew effect stands for the fact that in societies rich tend to get richer and the potent even more powerful. Here we investigate a…
Imitating emotions instead of strategies in spatial games elevates social welfare
Attila Szolnoki, Neng-Gang Xie, Chao Wang +1
The success of imitation as an evolutionary driving force in spatial games has often been questioned, especially for social dilemmas such as the snowdrift game, where the most prof…
