View source for Strategy (in game theory)

A method of action of a player or coalition that is possible under the rules of a strategic game (see [[Games, theory of]]). In games in normal form (see [[Non-cooperative game]]), the direct description of sets of strategies is part of the  "rules"  of the game. In a [[positional game]] (see also [[Dynamic game]]) strategies are not defined directly by the rules of the game, but indirectly on the basis of it. If in a non-cooperative game the choice of strategies is fixed (for example, by an optimality principle), then the game becomes non-strategic (see [[Cooperative game]]).
