Game theory (the so-called game theory) was first put forward by some mathematicians at the beginning of this century, which involves expressing the game skills of chess players with mathematical formulas. From 65438 to 0944, the great mathematician john neumann met the economist Oscar Morgenstein at Princeton University and jointly published the book Game Theory and Economic Behavior, which marked the great progress of strategic game theory and successfully combined game theory with economic analysis. Since then, Princeton University has become the research center of world game theory. From 65438 to 0950, johnf nash, a 22-year-old doctor of mathematics, published two epoch-making papers in succession: Equilibrium Point of N-person Game and Bargaining Problem. The following year, he published "Non-cooperative Countermeasures". All these laid a solid foundation for the non-cooperative game theory and the bargaining theory of cooperative game, and made pioneering contributions to the formation of a mature game theory discipline in the 1950 s.
