The common name for the concept of a zero-sum game is simply "zero-sum." A zero-sum game is a situation in game theory where the total gains and losses among participants equal zero; one participant's gain is exactly matched by another's loss. This concept is often applied in competitive scenarios such as games, economics, and negotiations. In a zero-sum environment, the resources are fixed, and any advantage gained by one party directly results in a disadvantage to another. The idea emphasizes the competitive nature of the interaction, contrasting with positive-sum games where cooperation can lead to benefits for all participants.
