A Nash equilibrium is a strategy profile (a strategy profile specifies a strategy for every player, e.g. in the above prisoners' dilemma game (cooperate, defect) specifies that prisoner 1 plays cooperate and prisoner 2 plays defect) in which every strategy is a best response to every other strategy played. A strategy by a player is a best response to another player's strategy if there is no other strategy that could be played that would yield a higher pay-off in any situation in which th… Witryna13 wrz 2007 · The Generalized Nash equilibrium problem is an important model that has its roots in the economic sciences but is being fruitfully used in many different fields.

Witryna4 lis 2024 · The Nash equilibrium is a powerful solution concept in large part because of the following: Nash’s existence theorem: In all finite games (i.e. games with a finite number of players and strategies per player), there exists at least one Nash equilibrium. We will almost always be able to find at least one Nash equilibrium. WitrynaNash equilibrium is the most widely used solution concept in game theory.
