Explain the concept of Nash equilibrium.

Nash equilibrium is a concept in game theory that describes a situation where each player in a game makes the best decision possible, given the decisions of the other players. In other words, it is a state where no player has an incentive to change their strategy, assuming that all other players' strategies remain unchanged. Nash equilibrium is reached when each player's strategy is the best response to the strategies chosen by the other players. It is named after John Nash, the mathematician who developed the concept.
