Define payoff matrix in game theory
WebThe payoff matrix is simply a double entry table, with all the payments made by one player to the other, for each strategy adopted, like in Table 6.13-1. As the payment of one player is equal to the gain of the other player, the game is called zero-sum (which is a type of constant-sum game): Table 6.13-1. Payoff matrix.

WebSymmetric game. In game theory, a symmetric game is a game where the payoffs for playing a particular strategy depend only on the other strategies employed, not on who is playing them. If one can change the identities of the players without changing the payoff to the strategies, then a game is symmetric. Symmetry can come in different varieties. WebThe most famous example from game theory is the following game called “The Prisoners’ Dilemma.” Rosemary and Colin have been arrested by the police as suspects. The police question them separately in different rooms. Each can either snitch on the other or can keep quiet. The payoff matrix looks like this: snitch keep quiet snitch (−2 ...
