==Strategies in game theory==

In [http://en.wikipedia.org/wiki/Game_theory game theory], a strategy refers to one of the [[options]] that a player can choose. That is, every player in a [[Competition|non-cooperative]] game has a set of possible strategies, and must [[choose]] one of the choices.

A strategy must specify what [[action]] will happen in each [[contingent]] [[state]] of the [[game]] - e.g. if the opponent does A, then take action B, whereas if the opponent does C, take action D.

Strategies in game theory may be [[random]] (mixed) or [[deterministic]] (pure). That is, in some games, players choose mixed strategies. Pure strategies can be [[thought]] of as a special case of mixed strategies, in which only [[probabilities]] 0 or 1 are assigned to [[actions]].
