In fully cooperative games players will opt to form coalitions when the value of the payoff is equal to or greater than if they were to work alone.[1] The focus of the game is to find acceptable distributions of the payoff of the grand coalition. Distributions where a player receives less than it could obtain on its own, without cooperating with anyone else, are unacceptable - a condition known as individual rationality. Imputations are distributions that are efficient and are individually rational.
