A Zero-Sum Game is a situation in which one person's gain is exactly balanced by the loss of another person or group. In other words, the total amount of resources or value in the system does not change, and any gain by one party must come at the expense of another.Zero-sum games are common in many areas of life, including economics, politics, and sports.For example, in a two-person market transaction, if one person gains from the transaction, the other person must have lost the same amount. In a game of chess, each player's moves and strategies are aimed at capturing the opponent's pieces, and the total number of pieces on the board remains constant.In game theory, the concept of a zero-sum game is important because it helps to understand the incentives and strategies of the players involved. In a zero-sum game, the players have conflicting interests, and their decisions and actions can have significant consequences for each other. Understanding the zero-sum nature of the game can help players make informed decisions and allocate resources more efficiently.In conclusion, a zero-sum game is a situation in which one person's gain is exactly balanced by another person's loss, and the total amount of resources or value in the system does not change. This concept is important in understanding the incentives and strategies of the players involved in a situation and can help to make more informed decisions.
