The most prominent studies of cooperation in sociology proceed from some kind of rationality assumption. There are basically two groups of studies, one starting from the assumption of rational egoists and the other starting from the assumption of social rationality in which other regard has a prominent place. The studies based on the assumption of rational egoists is strongly inspired by (mostl...

An active participation of players in evolutionary games depends on several factors, ranging from personal stakes to the properties of the interaction network. Diverse activity patterns thus have to be taken into account when studying the evolution of cooperation in social dilemmas. Here we study the weak prisoner's dilemma game, where the activity of each player is determined in a probabilisti...

tion of cooperation’ published by Biology to mark its 50th anniversa This article is a brief introduction to the special issue ‘Evoluthe Journal of Theoretical ry. Cooperation is a favorite topic among evolutionary biologists because it seems to be at variance with natural selection. Why should one individual help another who is a potential competitor in the struggle for survival? Yet cooperati...

Abstract A cohesive network keeps groups together and enables members to communicate about cooperate for public goods. For ongoing cooperation, group have know if their or defect, but this information—mostly through gossip—is threatened by noise biases. If there are redundant information channels, however, errors in monitoring transmission one imperfect channel can, some degree, be corrected an...

Social dilemmas have guided research on mutual cooperation for decades, especially the two-person social dilemma. Most famously, Tit-for-Tat performs very well in tournaments of Prisoner’s Dilemma. Nevertheless, they treat options to cooperate or defect only as an atomic action, which cannot satisfy complexity real world. In recent research, these were temporally extended. Here, we propose a no...

Aggregated phenomena in social sciences and economics are highly dependent on the way individuals interact. To help understanding the interplay between socio-economic activities and underlying social networks, this paper studies a sequential prisoner’s dilemma with binary choice. It proposes an analytical and computational insight about the role of endogenous networks in emergence and sustainab...
