Indirect reciprocity describes a class of reputation-based mechanisms which may explain the prevalence of cooperation … implementation occur. It has thus been claimed that for indirect reciprocity to stabilize cooperation, reputation assessments must be … observed provides ample possibilities for stable cooperation to emerge even under substantial rates of implementation errors. …

indirect reciprocity in the context of the evolution of cooperation, basic models of social dilemma situations, the path taken … in the elaboration of mathematical analysis using evolutionary game theory, the discovery of image scoring norms, and the …

mechanisms for sustaining cooperation. We present a novel intuitive combination of strategies that sustains cooperation in … essentially the unique mechanism to support full cooperation, and it is robust to various perturbations. Finally, we extend the … characterize which observation structure is optimal for sustaining cooperation. …

Intensive studies on indirect reciprocity have explored rational assessment rules for maintaining cooperation and … hybrid-assessment scheme in which players use both assessment systems and by using evolutionary game theory. We calculated … replicator equations using the expected payoffs of three strategies: unconditional cooperation, unconditional defection, and …

conditionally cooperative preferences. Cooperation generated by this type of preferences is notoriously unstable, as individuals …-shared conclusion that cooperation observed in experiments (and its collapse) is mostly driven by imperfect reciprocity. In this study …

artificial intelligence may or may not be cooperative. We study the deter-minants and forms of algorithmic cooperation in the … prisoner’s dilemma games played by humans in the lab. We find that the same factors that increase human cooperation largely … also determine the cooperation rates of algorithms. However, algorithms tend to play different strategies than humans …

This paper asks whether population growth is conducive to the sustainability of cooperation. A simple model is … of the sustainability of cooperation of the appearance of the mutants in a population that is not growing, and in one … that is growing. It is shown that the ex-ante probability of sustaining the cooperation strategy is higher for a community …
