• The Nash equilibrium is a decision theorem in game theory that states that a player can achieve a desired outcome without deviating from their original strategy.

  • In a Nash equilibrium, each player’s strategy is optimal when considering the decisions of other players. Every player wins because everyone gets the desired result.
  • The prisoner’s dilemma is a common game theory example that adequately demonstrates the Nash equilibrium effect.
  • The Nash equilibrium is often discussed in connection with the dominant strategy, which states that the strategy chosen by the actor will lead to the best outcomes of all possible strategies that can be used, regardless of the strategy used by the opponent.
  • Nash equilibrium does not always mean choosing the most optimal strategy.
