So for loyal this -1 payoff and for FinkMoreSo we need to see which one will get him higher payoff. So for loyal this -1 payoff and for Fink very Gio payoff. So obviously 0 is greater than minus 1 so this is the best strategy.

How many pure strategy Nash equilibria are there?

two pure-strategy Nash equilibriaThere are two pure-strategy Nash equilibria, (yes, yes) and (no, no), and no mixed strategy equilibria, because the strategy "yes" weakly dominates "no".

Does every game have a pure Nash equilibrium?

Pure strategy Nash equilibria are Nash equilibria where all players are playing pure strategies. Mixed strategy Nash equilibria are equilibria where at least one player is playing a mixed strategy. While Nash proved that every finite game has a Nash equilibrium, not all have pure strategy Nash equilibria.

Can a game have multiple mixed strategy equilibrium?

In a finite game, there is always at least one mixed strategy Nash equilibrium. This has been proven by John Nash[1]. There can be more than one mixed (or pure) strategy Nash equilibrium and in degenerate cases, it is possible that there are infinitely many.

How many pure strategies are there?

A pure strategy profile for the game will contain exactly 1 strategy for each player.

How do you determine the number of pure strategies?

Therefore the number of possible pure strategies is equal to the number of ways you can pick an action from information set 1 times the number of ways you can pick an action from information set 2, etcetera, up to information set N. In otherwords, it is equal to ∏Nn=1Mn.

What is a pure strategy game?

A pure strategy is a term used to refer to strategies in Game theory. Each player is given a set of strategies, if a player chooses to take one action with probability 1 then that player is playing a pure strategy.

What are the equilibria of the game?

Nash Equilibrium is a game theory concept that determines the optimal solution in a non-cooperative game in which each player lacks any incentive to change his/her initial strategy.

What is a pure game?

In a pure strategy, players adopt a strategy that provides the best payoffs. In other words, a pure strategy is the one that provides maximum profit or the best outcome to players. Therefore, it is regarded as the best strategy for every player of the game.

What is the difference between pure and mixed strategy under game theory?

A pure strategy determines all your moves during the game (and should therefore specify your moves for all possible other players' moves). A mixed strategy is a probability distribution over all possible pure strategies (some of which may get zero weight).

How do you calculate mixed strategy equilibrium?

Example: There can be mixed strategy Nash equilibrium even if there are pure strategy Nash equilibria. At the mixed Nash equilibrium Both players should be indifferent between their two strategies: Player 1: E(U) = E(D) ⇒ 3q = 1 − q ⇒ 4q = 1 ⇒ q = 1/4, Player 2: E(L) = E(R) ⇒ p = 3 × (1 − p) ⇒ 4p = 3 ⇒ p = 3/4.
