Nash equilibrium is game theory that says the optimal outcome of a game is achieved when there is no deviation from the initial strategy.
It occurs when a player do not change his/her own chosen strategy after considering his opponent to get the best outcome.
A player strategy during game is believed to be optimal and should not be changed for the opponent irrespective of the person strategy. If eventually a strategy is changed, it may not attract any compensation.
