Can there be multiple mixed strategy Nash equilibria?

There can be more than one mixed (or pure) strategy Nash equilibrium and in degenerate cases, it is possible that there are infinitely many. In a well-defined sense (open and dense in payoff-space), almost every finite game has a finite and odd number of mixed strategy Nash equilibria.

Is there a Nash equilibrium in every game?

In game theory, the Nash equilibrium, named after the mathematician John Forbes Nash Jr., is the most common way to define the solution of a non-cooperative game involving two or more players. Nash showed that there is a Nash equilibrium for every finite game: see further the article on strategy.

How do you calculate Nash equilibrium?

To find the Nash equilibria, we examine each action profile in turn. Neither player can increase her payoff by choosing an action different from her current one. Thus this action profile is a Nash equilibrium. By choosing A rather than I, player 1 obtains a payoff of 1 rather than 0, given player 2’s action.

How many Nash equilibrium can a game have?

one Nash equilibrium
The best situation is when a game has one Nash equilibrium. If there are multiple Nash equilibria, then there is some hope that only one of them is admissible. In this case, it is hoped that the rational players are intelligent enough to figure out that any nonadmissible equilibria should be discarded.

How do you find the Nash equilibrium of a game?

To find the Nash equilibria, we examine each action profile in turn. Firm 2 can increase its payoff from 1 to 2 by choosing the action Y rather than the action X. Thus this action profile is not a Nash equilibrium. Firm 1 can increase its payoff from 1 to 2 by choosing the action Y rather than the action X.
