In game theory, the Nash equilibrium (named after John Forbes Nash, who proposed it) is a kind of solution concept of a game involving two or more players. The profit of firm i is revenue minus cost. In a Nash equilibrium, each player is assumed to know the equilibrium strategies of the other players, and no one has anything to gain by changing only one's. For example. To calculate the Nash equilibrium, the best response functions of the firms must first be calculated. Ele. In general, the optimal theory dictates that the player is always making the decision that returns the most profit in the long run. In game theory, a subgame perfect equilibrium is a refinement of a Nash equilibrium used in dynamic games. In a non-Bayesian game, a strategy profile is a Nash equilibrium if every strategy in that profile is a best response to every other strategy in the profile;. A strategy profile is a subgame perfect.
