What is Nash equilibrium example?

Example: coordination between players with different preferences. Two firms are merging into two divisions of a large firm, and have to choose the computer system to use. … Neither player can increase her payoff by choosing an action different from her current one. Thus this action profile is a Nash equilibrium.

How many pure strategies does each player have?

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

What is the Nash equilibrium in pure strategies?

A pure-strategy Nash equilibrium is an action profile with the property that no single player i can obtain a higher payoff by choosing an action different from ai, given every other player j adheres to aj. For example, a game involves two players, each of whom could choose two available actions, which are X and Y.

What is pay of matrix?

A payoff matrix is a tool that is used to simplify all of the possible outcomes of a strategic decision. It is a visual representation of all the possible strategies and all of the possible outcomes.

Is a pure strategy a dominant strategy?

If there is a pure strategy that dominates every other pure strategy, then it must also dominate every other mixed strategy. If there is no dominant strategy in pure strategies, there cannot be one in mixed strategies either.

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 singleton game theory?

A game with perfect information is such that at any stage of the game, every player knows exactly what has taken place earlier in the game; i.e. every information set is a singleton set. Any game without perfect information has imperfect information.

What is matrix form in game theory?

The matrix provided is a normal-form representation of a game in which players move simultaneously (or at least do not observe the other player’s move before making their own) and receive the payoffs as specified for the combinations of actions played.
