Integrating neighborhoods in the evaluation of fitness promotes cooperation in the spatial prisoner’s dilemma game

Wang, Zhen; Du, Wen-Bo; Cao, Xian-Bin; Zhang, Lian-Zhong - In: Physica A: Statistical Mechanics and its Applications 390 (2011) 7, pp. 1234-1239

A fundamental question of human society is the evolution of cooperation. Many previous studies explored this question … undoubted fact is that the environment plays an important role in the individual development. Inspired by these phenomena, we ….e., integrating neighborhoods in the evaluation of fitness, promotes cooperation. If we enhance the value of u, the invasion of …

Promotion of cooperation by aspiration-induced migration

Lin, Ying-Ting; Yang, Han-Xin; Wu, Zhi-Xi; Wang, Bing-Hong - In: Physica A: Statistical Mechanics and its Applications 390 (2011) 1, pp. 77-82

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...

Critical social networks

Turalska, M.; West, B.J. - In: Physica A: Statistical Mechanics and its Applications 395 (2014) C, pp. 466-475

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...
