http://www.bio.utexas.edu/faculty/pianka/ESS.pdf Webevolutionarily stable strategy, or ESS, is a mathemati-cal definition for an optimal choice of strategy under such conditions. Interactions between two individuals can be de-picted as a mathematical game between two players. A branch of mathematics, called game theory, seeks to find the best strategy to play in any given carefully defined game.
