What Is Game Theory

When exploring what is game theory, it's essential to consider various aspects and implications. Game theory | Definition, Facts, & Examples | Britannica. Game theory, branch of applied mathematics that provides tools for analyzing situations in which parties, called players, make decisions that are interdependent. Development and basics of game theory | Britannica. Game theory was originally developed by John von Neumann and Oscar Morgenstern in their book The Theory of Games and Economic Behavior (1944). In a typical game, or competition with fixed rules, “players” try to outsmart one another by anticipating the others’ decisions, or moves.

Nash equilibrium | Definition, Examples, & Facts | Britannica. Game theory uses mathematics to model and analyze situations in which decisions are interdependent. While it can be used to model recreational games such as Monopoly or poker, it is often used to analyze topics of real-world interest, including economics and military strategy.

Game theory does not attempt to state what a player’s goal should be; instead, it shows how a player can best achieve his goal, whatever that goal is. Von Neumann and Morgenstern understood this distinction; to accommodate all players, whatever their goals, they constructed a theory of utility. Definition, Example, Game Theory, & Facts - Britannica. This is shown by thought experiments known as “prisoners’ dilemmas,” which played an increasingly important role in discussions of ethical theory in the late 20th century (see also game theory). The basic prisoners’ dilemma is an imaginary situation in which two prisoners are accused of a crime.

All in all, game theory holds out great promise not only for advancing the understanding of strategic interaction in very different settings but also for offering prescriptions for the design of better auction, bargaining, voting, and information systems that involve strategic choice. Optimal strategy | logic | Britannica.

It's important to note that, collective action problem | Causes, Solutions & Examples | Britannica. Game theory demonstrates that collective action is possible even without institutions supporting it. Empirical analyses of how people mobilize demonstrate the myriad ways in which collective action problems are overcome every day. Biography, Game Theory, Nobel Prize, & Facts - Britannica. Nash thus established the mathematical principles of game theory, a branch of mathematics that examines the rivalries between competitors with mixed interests.

Nash showed that for any finite game, all the players can arrive at an optimal outcome, known as the Nash equilibrium or the Nash solution, when considering the possible actions of the ...
