WitrynaBertrand Nash equilibrium is a key concept in game theory that describes a situation in which each player in a game has no incentive to change their strategy. This occurs when each player has chosen the best possible strategy given the strategies of the other players. In other words, no player can improve their situation by changing their strategy.
