Web1. apr 2024 · The Basics of Nash Equilibrium. Nash equilibrium is a term commonly used in game theory, particularly in economics. This concept was developed by John F. Nash Jr. and refers to a state where no player in a game can have their outcome improved by unilaterally changing their strategy, assuming the other players’ strategies remain unchanged. Web1 Describing Mixed Strategy Nash Equilibria Consider the following two games. The –rst game is one you might be familiar with: Rock, Paper, Scissors. In case you are not, in this game there are 2 players who simultaneously determine which object to form with their –ngers. Each player has 3 strategies Œform a Rock, form Paper, or form Scissors.

In a Nash equilibrium, each player is assumed to know the equilibrium strategies of the other players, and no one has anything to gain by changing only one's own strategy.
