Nash equilibrium theorem

WitrynaIn 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 … Witryna30 lis 2024 · Nash equilibrium is a game theory concept where optimal outcome is when there can don incentive for players to deviate from hers initial strategy.

WitrynaA Nash equilibrium is a pair consisting of a mixed strategy p for A and a mixed strategy q for B such that: For every mixed strategy p ′ for A, p ′ ⋅ A q ≤ p ⋅ A q. For every mixed strategy q ′ for B, p ⋅ B q ′ ≤ p ⋅ B q. (The idea is that p ⋅ A q is the expected payoff to player A when A chooses mixed strategy p and B chooses q.
