Direct reciprocity is a powerful mechanism for the evolution of cooperation on the basis of
repeated interactions,,–. It requires that interacting individuals are sufficiently equal, such …

Direct reciprocity is a powerful mechanism for cooperation in social dilemmas. The very logic
of reciprocity, however, seems to require that individuals are symmetric, and that everyone …

In multi-player games n individuals interact in any one encounter and derive a payoff from
that interaction. We assume that individuals adopt one of two strategies, and we consider …

We model the interaction between science and technology using an evolutionary game
theoretic framework. Conflictual rather than synergistic relation between science and …

The existence of cooperation is problematic for those who view the world through an
evolutionary lens. Although natural selection disfavors unconditional cooperation …

The evolution of social behavior has been the focus of many theoretical investigations,
which typically have assumed infinite populations and specific payoff structures. This paper …

Many biological and social systems show significant levels of collective action. Several
cooperation mechanisms have been proposed, yet they have been mostly studied …

Strategies for sustaining cooperation and preventing exploitation by selfish agents in
repeated games have mostly been restricted to Markovian strategies where the response of …

As one of the mechanisms that are supposed to explain the evolution of cooperation among
unrelated individuals, costly punishment, in which altruistic individuals privately bear the …

Evolution of cooperation by reciprocity has been studied using two-player and n-player
repeated prisoner's dilemma games. An interesting feature specific to the n-player case is …
