Evolution of extortion in Iterated Prisoner's Dilemma games.

The Evolution of Extortion in Iterated Prisoner’s Dilemma Games

Evolution of extortion in structured populations

Extortion strategies can dominate any opponent in an iterated prisoner's dilemma game. But if players are able to adopt the strategies performing better, extortion becomes widespread and evolutionary unstable. It may sometimes act as a catalyst for the evolution of cooperation, and it can also emerge in interactions between two populations, yet it is not the evolutionarily stable outcome. Here ...

From extortion to generosity, evolution in the Iterated Prisoner's Dilemma.

Recent work has revealed a new class of "zero-determinant" (ZD) strategies for iterated, two-player games. ZD strategies allow a player to unilaterally enforce a linear relationship between her score and her opponent's score, and thus to achieve an unusual degree of control over both players' long-term payoffs. Although originally conceived in the context of classical two-player game theory, ZD...

Evolutionary Extortion and Mischief: Zero Determinant strategies in iterated 2x2 games

This paper studies the mechanisms, implications, and potential applications of the recently discovered class of Zero Determinant (ZD) strategies in iterated 2x2 games. These strategies were reported to successfully extort pure economic maximizers, and to mischievously determine the set of feasible long-term payoffs in iterated Prisoners’ Dilemma by enforcing linear constraints on both players’ ...

Extortion and Evolution in the Iterated Prisoner's Dilemma

The Prisoner’s Dilemma is a two player game where playing rationally leads to a suboptimal outcome for both players. The game is simple to analyze, but when it is played repeatedly, complex dynamics emerge. Recent research has shown the existence of extortionate strategies, which allow one player to win at least as much as the other. When one player plays such a strategy, the other must either ...

An Experimental Study of N-Person Iterated Prisoner's Dilemma Games

The Iterated Prisoner’s Dilemma game has been used extensively in the study of the evolution of cooperative behaviours in social and biological systems. There have been a lot of experimental studies on evolving strategies for 2-player Iterated Prisoner’s Dilemma games (2IPD). However, there are many real world problems, especially many social and economic ones, which cannot be modelled by the 2...
