'''Game theory''' is a mathematical theory in [[economics]] that studies situations in which players choose different actions in an attempt to maximize their profits. It Provides a formal approach to the study of strategies and extends the simpler optimization 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.  

'''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 was developed in 1944, by [[John von Neumann]] and [[Oskar Morgenstern]], and was popularized in the 2001 film '''A Beautiful Mind''', staring [[Russell Crowe]] as mathematician and game theorist [[John Forbes Nash]].
