In this paper we revise Reinforcement Learning and adaptiveness in Multi-Agent Systems from an Evolutionary Game Theoretic perspective. The discussion will be focused on the following questions: What distinguishes the evolutionary approach from the rationalistic? What are the most important findings in evolutionary game theory so far? We consider an integro-differential model for evolutionary game theory which describes the evolution of a population adopting mixed strategies.

Weibull. The investigation of cooperation in some classical evolutionary games on populations where the network of interactions among individuals is of the scale-free type is extended and it is shown that the update rule, the payoff computation and the timing of the operations have a marked influence on the transient dynamics and the amount Jan 14, 2002 · Evolutionary game theory originated as an application of the mathematical theory of games to biological contexts, arising from the realization that frequency dependent fitness introduces a strategic aspect to evolution. Feb 6, 2004 · Evolutionary game theory is formulated in terms of phenotypes, thereby ignoring the complexity of the genotype-phenotype mapping. Some time after the emergence of traditional game theory, biologists realized the potential of game theory to formally study adaptation and coevolution of biological populations, particularly in contexts where the fitness of a phenotype depends on the composition of the population (Hamilton, 1967). But in The Descent of Man, in the context of sexual selection, he anticipated many of the ideas of evolutionary game theory.

How cooperation or altruism behavior could prevail in social dilemma then becomes a problematic issue. Darwin focused mostly on evolution and adaptation of an organism to the environment in which it was situated. What is powerful about evolutionary game theory is that cooperation strategies are chosen by bounded rational actors and success for a strategy is defined in terms of the number of copies of itself (Hofbauer and Sigmund, 1988). P An individual of type τ uses a mixed strategy τ = i q i s i, with all q i ≥0. A detailed table of contents and Chapter 1 can be downloaded here. ISBN: ‎9780262061414. Package.
