Excessive abundance of common resources deters social responsibility
Xiaojie Chen, Matjaž Perc
Izvirni znanstveni članek
Oznake: socialna dilema;evolucijske igre;javne dobrine;izobilje;fazni prehodi;fizika socioloških sistemov;social dilemma;evolutionary games;public goods;abundance;phase transitions;physics of social systems;
We study the evolution of cooperation in the collective-risk social dilemma game, where the risk is determined by a collective target that must be reached with individual contributions. All players initially receive endowments from the available amount of common resources. While cooperators contribu ...

In the framework of evolutionary games with institutional reciprocity, limited incentives are at disposal for rewarding cooperators and punishing defectors. In the simplest case, it can be assumed that, depending on their strategies, all players receive equal incentives from the common pool. The que ...

Evolution of public cooperation in a monitored society with implicated punishment and within-group enforcement
Xiaojie Chen, Tatsuya Sasaki, Matjaž Perc

Monitoring with implicated punishment is common in human societies to avert freeriding on common goods. But is it effective in promoting public cooperation? We show that the introduction of monitoring and implicated punishment is indeed effective, as it transforms the public goods game to a coordina ...

Probabilistic sharing solves the problem of costly punishment

Cooperators that refuse to participate in sanctioning defectors create the secondorder free-rider problem. Such cooperators will not be punished because they contribute to the public good, but they also eschew the costs associated with punishing defectors. Altruistic punishers - those that cooperate ...

Adaptive and bounded investment returns promote cooperation in spatial public goods games
Xiaojie Chen, Yongkui Liu, Yonghui Zhou, Long Wang, Matjaž Perc
Izvirni znanstveni članek
Oznake: kooperacija;javne dobrine;socialne dileme;fizika socioloških sistemov;cooperation;public goods;social dilemmas;physics of social systems;
The public goods game is one of the most famous models for studying the evolution of cooperation in sizable groups. The multiplication factor in this game can characterize the investment return from the public good, which may be variable depending on the interactive environment in realistic situatio ...

Win-stay-lose-learn promotes cooperation in the spatial prisoner's dilemma game

Izvirni znanstveni članek
Oznake: socialne dileme;dilema zapornika;kooperacija;mreže;social dilemmas;prisoner's dilemma;cooperation;networks;
Holding on to one's strategy is natural and common if the later warrants success and satisfaction. This goes against widespread simulation practices of evolutionary games, where players frequently consider changing their strategy even though their payoffs may be marginally different than those of th ...

Beyond pairwise strategy updating in the prisoner's dilemma game

In spatial games players typically alter their strategy by imitating the most successful or one randomly selected neighbor. Since a single neighbor is taken as reference, the information stemming from other neighbors is neglected, which begets the consideration of alternative, possibly more realisti ...
