Nash equilibrium (or equilibria) sp: It encompasses a wide range of applications some of which are listed below: There are limited number of competitors such that n ≥ 2. An element of a matrix that is simultaneously minimum of the row in which it occurs and the maximum of the column in which it occurs is a saddle point of the game. Minimax — is a decision rule used in decision theory, game theory, statistics and philosophy for minimizing the possible loss for a worst case (maximum loss) scenario. The below mentioned article provides a close view on the game theory ii. Dilemma is an example of a problem analyzed in game theory where two rational people acting in their own best interests do not necessarily produce optimal results. Vii ≡ v, then the game has a saddle point, v is the value of the game, and the optimal strategies for players i and ii are the row and column that guarantee v. Respectivechoice targets is called the value, v, of the game. The graph above would be an example of a saddle surface; saddle point definition, a point at which a function of two variables has partial derivatives equal to zero but at which the function has neither a maximum nor a minimum value. We are trying to maximize the value of the surface by our choice in one dimension and.
