Dominant strategy , Game Theory

A strategy is dominant if, no matter what the other players do, the strategy earns a player a bigger payoff than the other. Hence, a method is dominant if it's invariably higher than the other strategy, for any profile of different players' actions. Counting on whether or not "better" is outlined with weak or strict inequalities, the strategy is termed strictly dominant or weakly dominant. If one strategy is dominant, than all others are dominated. For instance, within the prisoner's dilemma, every player contains a dominant strategy.
