is1ConvexGame checks if a TU game is 1-convex. A TU game is 1-convex if and only if the following condition holds true: Let S be a nonempty coalition. Whenever all players outside S receive their payoffs according to the utopia payoff of the game, then the remaining part of the total savings is at least v(S).
