Check if game is additive

Description

Checks if a TU game with n players is additive.
In an additive game for any two disjoint coalitions S and T the value of the union of S and T equals the sum of the values of S and T. In other words, additive games are constant-sum and the imputation set of an additive game consists of exactly one point.

Usage

isAdditiveGame(v)

Arguments

v

Numeric vector of length 2^n - 1 representing the values of the coalitions of a TU game with n players

Value

TRUE if the game is additive, else FALSE
