... So different equilibria result in different payoffs. If we can’t predict which Nash equilibrium will be reached, we also can’t predict the payoffs. In this lecture we will address these critiques, showing that players arrive at an equilibrium by playing a game repeatedly and using learning rules to ...

Lecture 2 (portion) 1 Two Player Games

... This is an example of a zero-sum game where the sum of the payoffs of the two players is zero for all strategies. The players are assumed to be rational, the row player attempts to minimize the payoff while the column player attempts to maximize it. For example a run of Roshambo might proceed as fol ...

Staying wins you the admiration of your peers (a big payoff) only if the other player swerves. Swerving loses face if the other player stays. However, ...
