What is the history of Nash Equilibrium?

Nash Equilibrium, developed by John Nash in the 1950s, is a key concept in game theory. It describes a situation where no player can benefit by changing their strategy while the other players keep theirs unchanged.

How did John Nash come up with this idea?

Nash introduced the concept in his 1950 dissertation, where he aimed to extend the idea of equilibrium in non-cooperative games, building on earlier work by mathematicians like von Neumann and Morgenstern.

What are some real-world applications of Nash Equilibrium?

Nash Equilibrium is used in various fields, including economics, political science, and biology, to analyze competitive situations like market competition, auctions, and evolutionary strategies.

Can you give an example of Nash Equilibrium in action?

Sure! A classic example is the Prisoner's Dilemma, where two criminals must decide whether to cooperate or betray each other. The Nash Equilibrium occurs when both betray, as neither can improve their outcome by changing their decision unilaterally.
