Creating a Graph with Gambit: QRE Explained

[Cyn]

Hi,

How can you use Gambit to make a graph of the QRE (quantal response equilibrium).

Thank you.

Gambit can be used to graph the QRE (quantal response equilibrium) by using its graphical user interface. To do this, first create a new game in Gambit and select the strategic form of the game. Then enter the payoff matrix for each player in the game. Once the payoff matrix is entered, click on the ‘Solve’ button and select ‘Quantal Response Equilibrium’ from the drop-down menu. This will generate a QRE graph which shows the probability that each player will choose each strategy in the game. The graph can then be further customized with labels and colors.
