Evolutionary game theory

Weak evolutionarily stable strategy

A weak evolutionarily stable strategy (WESS) is a more broad form of evolutionarily stable strategy (ESS). Like ESS, a WESS is able to defend against an invading "mutant" strategy. This means the WESS cannot be entirely eliminated from the population. The definition of WESS is similar to ESS. Any strategy s is a weakly evolutionarily stable strategy (WESS) if for any strategy s*≠s: (i) u(s, s) > u(s*, s) or (ii) u(s, s) = u(s*, s) and u(s, s*) ≥ u(s*, s*). One example of WESS, in a prisoner's dilemma, is Tit-for-tat (a strategy that cooperates in the first interaction and then reciprocates the other player's action from the previous turn in all other iterations). (Wikipedia).

Game theory (3), more complicated strategies and equilibria.

This video elaborates on the concept of stable strategies and evolutionary equilibria to include polymorphisms of pure strategies and the evolution of mixed strategies such as phenotypic plasticity.

11. Evolutionary stability: cooperation, mutation, and equilibrium

Game Theory (ECON 159) 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. The informal

12. Evolutionary stability: social convention, aggression, and cycles

Game Theory (ECON 159) We apply the idea of evolutionary stability to consider the evolution of social conventions. Then we consider games that involve aggressive (Hawk) and passive (Dove) strategies, finding that sometimes, evolutionary populations are mixed. We discuss how such games ca

Game theory (2), the hawk:dove model.

This video examines the hawk:dove model and uses it to discuss the evolution of stable strategies. How this perspective leading us to understand the relative universality of stable sex ratios is discussed.

Abstract: Adaptive dynamics has shaped our understanding of evolution by demonstrating that, via the process of evolutionary branching, ecological interactions can promote diversification. The classical approach to study the adaptive dynamics of a system is to specify the ecological model
