Study Notes
Nash Equilibrium
- The Nash equilibrium is a concept in game theory that describes a state where no player can improve their outcome by unilaterally changing their strategy, assuming all other players keep their strategies unchanged.
Origin and Namesake
- The Nash equilibrium is named after John Nash, an American mathematician who introduced the concept in the 1950s.
Definition in Non-Cooperative Games
- In a non-cooperative game, a Nash equilibrium is defined as a set of strategies, one for each player, where no player can improve their payoff by changing their strategy, assuming all other players keep their strategies unchanged.
Constituents of a Nash Equilibrium
- A set of strategies constitutes a Nash equilibrium if no player has an incentive to deviate from their chosen strategy, given the strategies of all other players.
History of the Principle
- The principle of Nash equilibrium originated in the 1950s, introduced by John Nash.
Principles and Assumptions
- The Nash equilibrium is based on the assumption that all players are rational and act in their own self-interest.
Conditions for a Nash Equilibrium
- A set of strategy choices constitutes a Nash equilibrium if no player can improve their payoff by unilaterally changing their strategy, assuming all other players keep their strategies unchanged.
Contributions to the Principle
- Antoine Augustin Cournot, a French mathematician, laid the groundwork for the concept of Nash equilibrium through his work on oligopoly, which was later developed by John Nash.
Nash Equilibrium for Two Players
- For two players, Alice and Bob, with strategies A and B, a Nash equilibrium is defined as a pair of strategies (A, B) where neither player can improve their payoff by unilaterally changing their strategy, assuming the other player keeps their strategy unchanged.
