WebIn game theory, a solution concept is a formal rule for predicting how a game will be played. These predictions are called "solutions", and describe which strategies will be adopted by players and, therefore, the result of the game. The most commonly used solution concepts are equilibrium concepts, most famously Nash equilibrium.. Many solution … WebSo, it’s cleaner simply to eliminate the dominated strategy and just say that the system is ergodic, with the dominant strategy becoming fixated or almost fixated (one and only one member of the weakly dominated strategy would remain). There are some interesting connections between dominance, Nash equilibriums, ESS, and replicator dynamics. WebFor example, non-credible threats can be supported in Nash equilibrium.
