Fractional Pareto optimality is a strengthening of Pareto-optimality in the context of fair item allocation. An allocation of indivisible items is fractionally Pareto-optimal (fPO) if it is not Pareto-dominated even by an allocation in which some items are split between agents. This is in contrast to standard Pareto-optimality, which only considers domination by feasible (discrete) allocations.

'''<font color="#ff8000">部分帕累托最优(Fractional Pareto optimality)</font>'''是在物品公平分配的背景下对帕累托最优的一个加强。 即使是在一个分配过程中，一些物品在主体之间被分配，如果一个不可分割的物品的分配不是受帕累托支配的，那么它不是部分帕累托最优(fPO)。这与标准的帕累托最优相反，因为它只考虑可行(离散)分配的控制。
For a given system, the Pareto frontier or Pareto set is the set of parameterizations (allocations) that are all Pareto efficient. Finding Pareto frontiers is particularly useful in engineering. By yielding all of the potentially optimal solutions, a designer can make focused tradeoffs within this constrained set of parameters, rather than needing to consider the full ranges of parameters.
