Here, the coalition function v(S) assigns a worth to a coalition of players S. Because of the graph-restriction of the game, only the worth of the individual connected subgraphs are allowed to form coalitions of possible players. The sum of these individual coalitions T is then taken as the worth of the coalition S, where S is restricted by the graph G. For example, a coalition of players that form two unconnected subgraphs will be calculated by summing up the worth of the coalitions of the subgraphs instead of calculating the worth for all combined players. The set of graph restricted coalitions S/G (read as "S divided by G") is defined as:
