A social discounting model based on Tsallis’ statistics

Takahashi, Taiki - In: Physica A: Statistical Mechanics and its Applications 389 (2010) 17, pp. 3600-3603

Social decision making (e.g. social discounting and social preferences) has been attracting attention in economics, econophysics, social physics, behavioral psychology, and neuroeconomics. This paper proposes a novel social discounting model based on the deformed algebra developed in the...

Community structure and ethnic preferences in school friendship networks

González, M.C.; Herrmann, H.J.; Kertész, J.; Vicsek, T. - In: Physica A: Statistical Mechanics and its Applications 379 (2007) 1, pp. 307-316

Recently developed concepts and techniques of analyzing complex systems provide new insight into the structure of social networks. Uncovering recurrent preferences and organizational principles in such networks is a key issue to characterize them. We investigate school friendship networks from...

Robustness of cooperation in memory-based prisoner’s dilemma game on a square lattice

Ren, Guangming; Wang, Xingyuan - In: Physica A: Statistical Mechanics and its Applications 408 (2014) C, pp. 40-46

Cooperation in prisoner’s dilemma game can be promoted significantly by introducing memory effects. In this work, we … numerically investigated robustness of cooperation by introducing an attack probability, with which an individual in cooperation … vanishment of the cooperators. Our work could be helpful to understand the emergence of cooperation in systems consisting of …

Mixed strategy and coevolution dynamics in social networks

Zhong, Weicai; Abbass, Hussein A.; Bender, Axel; Liu, Jing - In: Physica A: Statistical Mechanics and its Applications 390 (2011) 2, pp. 410-417

We investigate coevolution dynamics of both individual strategies and social ties as they adapt within the snowdrift game with mixed strategies. We propose a partner selection mechanism based on the concept of trust. Here trust is considered an instrument for an individual both selecting the...

Promotion of cooperation induced by the interplay between structure and game dynamics

Fu, Feng; Chen, Xiaojie; Liu, Lianghuan; Wang, Long - In: Physica A: Statistical Mechanics and its Applications 383 (2007) 2, pp. 651-659

random from the neighbors of the punished agent. It is found that the promotion of cooperation is attributed to the entangled … extensive numerical simulations. Our results to some extent reflect the underlying mechanism promoting cooperation. …

Spatial social dilemmas: Dilution, mobility and grouping effects with imitation dynamics

Vainstein, Mendeli H.; Arenzon, Jeferson J. - In: Physica A: Statistical Mechanics and its Applications 394 (2014) C, pp. 145-157

We present an extensive, systematic study of the Prisoner’s Dilemma and Snowdrift games on a square lattice under a synchronous, noiseless imitation dynamics. We show that for both the occupancy of the network and the (random) mobility of the agents there are intermediate values that may...

Cooperative networks overcoming defectors by social influence

Gomez Portillo, Ignacio - In: Physica A: Statistical Mechanics and its Applications 394 (2014) C, pp. 198-210

We address the cooperation problem in structured populations by considering the prisoner’s dilemma game as a metaphor …. In this way, we conclude that in a structured system formed by a growing process, the cooperation evolves if the … theoretical solution of the cooperation problem among genetically unrelated individuals. …
