We conduct a study on the problem of fair allocation indivisible goods when maximin share [1] is used as measure fairness. Most current studies this notion are limited to case that valuations additive. In paper, we go beyond additive and consider cases submodular, fractionally subadditive, subadditive. give constant approximation guarantees for agents with submodular XOS valuations, logarithmic...
