'''Game theory''' is a branch of mathematics, most commonly applied in [[economics]], that studies situations in which players' outcomes are determined by their own choices as well as the choices of other players. It provides a formal approach to the study of strategic behavior and extends the simpler optimisation approach developed in neoclassical economics. Game theory can be viewed as a branch of decision theory in which players of the game interact with each other. A common example of game theory is the [[prisoner's dilemma]]. | '''Game theory''' is a branch of mathematics, most commonly applied in [[economics]], that studies situations in which players' outcomes are determined by their own choices as well as the choices of other players.
