We discuss evolution and game theory, and introduce the concept of evolutionary stability. We ask what kinds of strategies are evolutionarily stable, and how this idea from biology relates to concepts from economics like domination and Nash equilibrium.

An evolutionarily stable state is a dynamical property of a population to return to using a strategy, or mix of strategies, if it is perturbed from that strategy, or mix of strategies. The former concept fits within classical game theory , whereas the latter is a population genetics, dynamical system, or evolutionary game theory concept.

Our analysis showed that this effect arises from interactions among pioneering cells at the front of the expanding population, and revealed a simple, evolutionarily stable strategy for colonizing a When evolution favours a stable ratio of traits rather than one dominant trait.Check out Audible: http://bit.ly/AudibleVeAnimation by The Lyosacks: https://w Evolutionarily Stable Strategy (ESS) Theory. The concept of the evolutionarily stable strategy was first formulated by John Maynard Smith, who applied game theory to study the evolution of animal behaviors (Maynard Smith, 1974). Game theory essentially looks for the existence of strategy equilibria given the expected payoff of each strategy. An evolutionarily stable strategy (ESS) is an evolutionary strategy that, if adapted by a population, cannot be invaded by any deviating (mutant) strategy. The concept of ESS has been extensively studied and widely applied in ecology and evolutionary biology [M.

An evolutionarily stable strategy (ESS) is a strategy that no other feasible alternative can better, given that sufficient members of the population adopt it. The best strategy for an individual depends upon the strategy or strategies that other members of the same population adopt.

Thus, over time, the strategy mix should evolve to some type of optimal or stable state. Maynard Smith and Price (1973) have introduced the concept of ESS (evolutionarily stable strategy) to describe a stable state given strategy based on their assessment, it is now a hawk-dove ESS, compared to a hawk-dove evolutionary stable state. Such a strategy is called Bourgeois or the Retaliator. Such indi-viduals always play hawk if they are an owner and a dove if they are an intruder. Bourgeois strategy has been observed among some group only evolutionarily stable strategy based on random movement is the one where the dispersal rate is zero. Similar results have been obtained for other types of models [5–7]. The reason why random dispersal is not favored in heterogeneous environments is that it results in over De nition Another de nition for evolutionarily stable strategies: In a 2-player symmetric game, a strategy s is evolutionarily stable if: 1.(s;s) is a Nash equilibrium, and What does evolutionarily-stable-strategy mean?
