In his 1938 book Applications aux Jeux de Hasard and earlier notes, Émile Borel proved a minimax theorem for two-person zero-sum matrix games only when the pay-off matrix is symmetric and provided a solution to a non-trivial infinite game (known in English as Blotto game). In 1938, the Danish mathematical economist Frederik Zeuthen proved that the mathematical model had a winning strategy by using Brouwer's fixed point theorem. This paved the way for more general theorems. In 1913, Ernst Zermelo published Über eine Anwendung der Mengenlehre auf die Theorie des Schachspiels ( On an Application of Set Theory to the Theory of the Game of Chess), which proved that the optimal chess strategy is strictly determined. In his 1838 Recherches sur les principes mathématiques de la théorie des richesses ( Researches into the Mathematical Principles of the Theory of Wealth), Antoine Augustin Cournot considered a duopoly and presented a solution that is the Nash equilibrium of the game. In this letter, Waldegrave provided a minimax mixed strategy solution to a two-person version of the card game le Her, and the problem is now known as Waldegrave problem. He was an active Jacobite and uncle to James Waldegrave, a British diplomat. In 1713, a letter attributed to Charles Waldegrave analyzed a game called "le Her". In the 1650s, Pascal and Huygens developed the concept of expectation on reasoning about the structure of games of chance, and Huygens published his gambling calculus in De ratiociniis in ludo aleæ ( On Reasoning in Games of Chance) in 1657. Cardano's work on games of chance in Liber de ludo aleae ( Book on Games of Chance), which was written around 1564 but published posthumously in 1663, formulated some of the field's basic ideas. John Maynard Smith was awarded the Crafoord Prize for his application of evolutionary game theory.ĭiscussions on the mathematics of games began long before the rise of modern mathematical game theory. Wilson, fifteen game theorists have won the economics Nobel Prize. As of 2020, with the Nobel Memorial Prize in Economic Sciences going to game theorists Paul Milgrom and Robert B. Game theory has been widely recognized as an important tool in many fields. It was explicitly applied to evolution in the 1970s, although similar developments go back at least as far as the 1930s. Game theory was developed extensively in the 1950s by many scholars. Therefore, it is evident that game theory has evolved over time with consistent efforts of mathematicians, economists and other academicians. The second edition of this book provided an axiomatic theory of expected utility, which allowed mathematical statisticians and economists to treat decision-making under uncertainty. His paper was followed by the 1944 book Theory of Games and Economic Behavior, co-written with Oskar Morgenstern, which considered cooperative games of several players. Von Neumann's original proof used the Brouwer fixed-point theorem on continuous mappings into compact convex sets, which became a standard method in game theory and mathematical economics. Modern game theory began with the idea of mixed-strategy equilibria in two-person zero-sum game and its proof by John von Neumann. In the 21st century, the advanced game theories apply to a wider range of behavioral relations it is now an umbrella term for the science of logical decision making in humans, animals, as well as computers. The traditional methods of game theory addressed two-person zero-sum games, in which each participant's gains or losses are exactly balanced by the losses and gains of other participants. The concepts of game theory are used extensively in economics as well. It has applications in all fields of social science, as well as in logic, systems science and computer science. Game theory is the study of mathematical models of strategic interactions among rational agents.
