Nonzero-Sum Game. BIBLIOGRAPHY. In game theory, nonzero-sum games (more precisely known as nonconstant-sum games) include many examples in which the sum of the payoffs to the players varies according to the strategies chosen.These cases are often more relevant to issues in social science and public policy than are zero-sum (and more generally constant-sum) games.
Like poker, outperformance in the stock market is a zero-sum game. In other words, for every winner in the equity market there must be a loser. The losers in equity markets are usually retail investors and their managers who tend to overestimate their own prowess. The winners, of course, are typically institutional investors. These latter.
These are called zero-sum games because the sum of the outcomes for each player are always zero. A great example is playing poker, since every time one player wins money in a hand, all the other players lose that same amount (in total).

Zero-sum game definition is - a situation in which one person or group can win something only by causing another person or group to lose it. How to use zero-sum game in a sentence.
Constant sum: A game is constant sum 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.

Poker has served as a challenge problem for the fields of ar-. rium in two -player non -zero-sum games, and the existence of one would have sweeping surprising implications in compu-tational complexity theory (13, 14). Finding a Nash equilib-rium in zero -sum games with three or more players is at least as hard (because a dummy player can be added to the two-player game to make it a three.
Section 2.1 Introduction to Two-Person Zero-Sum Games. In all of the examples from the last section, whatever one player won, the other player lost. Definition 2.1.1. A two player game is called a zero-sum game if the sum of the payoffs to each player is constant for all possible outcomes of the game.

If avoiding a zero-sum game is an action choice with some probability for players, avoiding is always an equilibrium strategy for at least one player at a zero-sum game. For any two players zero-sum game where a zero-zero draw is impossible or non-credible after the play is started, such as Poker, there is no Nash equilibrium strategy other than avoiding the play.
A zero-sum game is also called a strictly competitive game while non-zero-sum games can be either competitive or non-competitive. Zero-sum games are most often solved with the minimax theorem which is closely related to linear programming duality, or with Nash equilibrium.
