Dilema do prisioneiro e dinâmicas evolucionárias

Abstract

In order to discuss evolutionary games based on the prisoner dilemma, first of all, the paper presents the well-known folk theorem conclusions on the repeated game context. Thus, it mentions the main assumptions and outcomes reached by Axelrod’s study on the evolution of cooperation. Then, the paper analyses three evolutionary models that takes in account strategies more complexes than the simple ones based on the repetition of the same cooperation or defection actions. The individuals drawn from a homogenous population adopt these strategies and participate in pairwise contests. The sequence of models looks for strategies that have more surviving capabilities. The main objective is not to show that Axerod’s conclusions are right, but, on the contrary, it is to demonstrate that they are wrong.
