Separately, game theory has played a role in online algorithms; in particular, the k-server problem, which has in the past been referred to as games with moving costs and request-answer games. [125] Yao's principle is a game-theoretic technique for proving lower bounds on the computational complexity of randomized algorithms , especially online ...
In game theory, a solution concept is a formal rule for predicting how a game will be played. These predictions are called "solutions", and describe which strategies will be adopted by players and, therefore, the result of the game. The most commonly used solution concepts are equilibrium concepts, most famously Nash equilibrium.
Findings from behavioral game theory will tend to have higher external validity and can be better applied to real world decision-making behavior. [14] Behavioral game theory is a primarily positive theory rather than a normative theory. [14] A positive theory seeks to describe phenomena rather than prescribe a correct action.
Constant sum: A game is a constant sum game if the sum of the payoffs to every player are the same for every single set of strategies. In these games, one player gains if and only if another player loses. A constant sum game can be converted into a zero sum game by subtracting a fixed value from all payoffs, leaving their relative order unchanged.
International Game Theory Review is a peer-reviewed academic journal published quarterly by World Scientific. It contains articles and surveys on theories and applications of game theory in socio-economic and political contexts and other related areas. Aside from regular articles on theory, methodology and application of games, it also includes ...
I took a shot at it: Game theorists respond by comparing their assumptions to those used in physics. Thus while their assumptions do not always hold, they can treat game theory as a reasonable scientific ideal akin to the models used by physicists. — RJH 16:55, 29 October 2005 (UTC) Bravo! I've replaced the sentence in the article.
In contrast, in classic game theory, even complex games are treated as single, monolithic objects. This makes the analysis of games hard to scale. Compositional game theory (CGT) aims to apply the modularity principle to game theory. The main motivation is to make it easier to analyze large games using software tools.
