Cooperative game theory is a branch of game theory that deals with the study of games where players can form coalitions, cooperate with one another, and make binding agreements. The theory offers mathematical methods for analysing scenarios in which two or more players are required to make choices that will affect other players wellbeing.
Cooperative game may refer to: Cooperative board game, board games in which players work together to achieve a common goal; Cooperative game theory, in game theory, a game with competition between groups of players and the possibility of cooperative behavior; Cooperative video game, a video game that allows players to work together as teammates
A traitor game or semi-cooperative game can be seen as a cooperative game with a betrayal mechanism. While, as in a standard cooperative game, the majority of players work towards a common goal, one or more players are secretly assigned to be traitors who win if the other player fail. Determining the identity of traitors is often central to ...
A cooperative video game is a video game that allows players to work together as teammates, usually against one or more non-player character opponents . Cooperative video games are often abbreviated as co-ops. The gameplay of cooperative games may be entirely cooperative or be limited to cooperative modes.
As non-cooperative game theory is more general, cooperative games can be analyzed through the approach of non-cooperative game theory (the converse does not hold) provided that sufficient assumptions are made to encompass all the possible strategies available to players due to the possibility of external enforcement of cooperation.
In cooperative game theory, the Shapley value is a method (solution concept) for fairly distributing the total gains or costs among a group of players who have collaborated. For example, in a team project where each member contributed differently, the Shapley value provides a way to determine how much credit or blame each member deserves.
Basic principles of co-opetitive structures have been described in game theory, a scientific field that received more attention with the book Theory of Games and Economic Behavior in 1944 and the works of John Forbes Nash on non-cooperative games. Coopetition occurs both at inter-organizational or intra-organizational levels.
An important problem in the theory of cooperative dynamic games is the time-consistency of a given imputation function (in Russian literature it is termed dynamic stability of optimality principle). Let say that a number of players has made a cooperative agreement at the start of the game.
