In game theory, a zero-sum game is a mathematical representation of a situation in which each participant’s gain or loss is exactly balanced by the losses or gains of the other participants. If the total gains of the participants are added up and the total losses are subtracted, they will sum to zero. Thus cutting a cake, where taking a larger piece reduces the amount of cake available for others, is an example of this. A zero-sum game is also called a strictly competitive game, as the pie cannot be enlarged by good negotiation and cooperation there is no incentive for cooperation between agents in these situations but in fact a strong attractor towards competition. In these games what the other loses you gain thus keeping track and comparing your state to that of your opponent makes sense. Zero-sum games are linear and additive the whole system is simply a summation of its constituent elements, thus they are essentially simple or non-complex.
