Evolutionary Game Theory

A particular branch of game theory, developed by evolutionary biologists from the 1970s, is detached from the initial theory. This is the evolutionary game theory, sometimes referred to as evolutionary games). Biologists have used the principles of game theory to model certain aspects of biological evolution, as described in the Darwinian paradigm. Evolutionary game theory has the advantage of avoiding the major problem of the classical game theory i.e. characterization of rational behavior and the need to anticipate the actions of other players. In fact, the debut classical game theory is proposed to reflect the behavior of rational players' interactions, that is to say, aware of the situations and thinking to increase their earnings. Faced with insurmountable difficulties introduced into the game by the notions of belief, information level and subjectivity of the players, the concept of rationality can never be identified. In evolutionary game any idea of strategic choice and advance and thus rationality is abandoned.

Game theorists, who tried since 1990 to limit the influence of rationality in the solution concept of the game and the players to pass relatively simple strategies, have turned to evolutionary game (www.ssc.wisc.edu). These games are far beyond biology and enjoyed considerable success in the 1990s, especially in economics, because they are based on simple behavioral assumptions. They assume that the strategies that persist in the evolutionary game are the ones who got the best gains over time. These are the political science professor Robert Axelrod and geneticist John Maynard Smith were the most prominent theorists of this branch of the theory of biological evolution applied to games.

In these evolutionary game players are living organisms: animals, plants, bacteria and viruses. The organisms of the same species or closely related species, are competing for limited resources. In their interactions these organizations are, ...
