In this paper we study the problem of finding fair and efficient allocations of a mixed manna, ie, a set M of discrete items that are goods/chores, among a set N of agents with additive valuations. We note that a mixed manna allows an item to be a good (positively valued) for some agents, and a chore (negatively valued) for others, and thereby strictly generalizes the extensively studied goods (chores) manna. To measure fairness and efficiency we consider the popular and well studied notions of maximin-share (MMS) and Pareto optimality (PO) respectively.An MMS allocation is one where every agent gets at least her MMS value. However,[6] showed that an MMS allocation may not always exist. This prompted a series of works on the efficient computation of 𝛼-MMS allocations, where every agent gets at least 𝛼 (1/𝛼) times her MMS value for a goods (chores) manna, for progressively better 𝛼∈[0, 1]; the best factor known so far is
