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. 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. The strategy employed by individuals (or ESS) is thought to depend on fitness: the better the strategy is at supporting fitness, the more likely the strategy is to be used.

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? A strategy that, when adopted by a population , is effective and unlikely to be replaced by another strategy. (noun) 2014-11-21 Learn the definition of 'evolutionarily stable strategy'.

Smith, On Evolution (1972)] but typically on … An ESS or evolutionarily stable strategy is a strategy such that, if all the members of a population adopt it, no mutant strategy can invade. -- Maynard Smith (1982). A population is said to be in an evolutionarily stable state if its genetic composition is restored by selection after a disturbance, provided the disturbance is not too large. Evolutionarily stable strategy is considered to constitute strategy that, as soon as it predominates in the population, will be more successful in every situation than any other minority strategy (Maynard Smith & Price 1973). Thus, if an allele that codes behaviour of an organism Evolutionarily Stable Strategies. The concept of the evolutionarily stable strategy, or ESS, is an important part of game theory.

Evolutionarily Stable Strategies and Game Dynamics PETER D. TAYLOR AND LEO B. JONKER Department of Mathematics, Queen’s Universi@, Kingston, Ontario, Canada K7L 3N6 Received I2 June 1977; revised 27 February I978 ABSTRACT We consider a class of matrix games in which successful strategies are rewarded by Evolutionarily Stable Strategies in our First Example. Let’s see what happens when we apply this definition to our example involving beetles competing for food. We will first check whether the strategy Small is evolutionarily stable, and then we will do the same for the strategy Large.
