Named after mathematician JOHN NASH, and central to game theory, Nash equilibrium refers to a situation in which individuals participating in a game pursue the best possible strategy while possessing the knowledge of the strategies of other players.
It works on the premise that the player cannot improve his/her position given the other players' strategy.
Nash equilibrium is sometimes referred to as the non-co-operative equilibrium because each player chooses his/her own strategy believing it is the best one possible, without collusion, and without thinking about the interests of either his opponent or the society in which he/she lives.
