"WebThe Shapley value ( Shapley (1953)) is one way to distribute the total gains to the players, assuming that they all collaborate. The amount that player i gets is then ϕi(v) = ϕi = ∑ S ⊆ N ∖ { i } S !(M − S − 1)! M! (v(S ∪ {i}) − v(S)), that is, a weighted mean over all subsets S of players not containing player i.
