The exact calculation of a single Shapley or Myerson value scales exponentially with the number of players in a game, as it is calculated as a sum over all coalitions 2 N -1 = 2 N /2. More often this scales to 2 N -1 • N when calculating all Shapley/Myerson values. While the worths of individual coalitions can be reused for subsequent values, the algorithmic complexity stays exponential for the number of players. For large player sets, this makes the calculation infeasible, especially for the Myerson value which additionally requires the computationally expensive operation of finding all subgraphs for a coalition.
