    NOTE: the following related problems are known to be computationally hard: Calculating the 1-of-MMS of a given agent is NP-hard even if all agents have additive preferences (reduction from partition problem). Deciding whether a given allocation is 1-of-MMS is co-NP complete for agents with additive preferences.
