Web[Caragiannis et al., 2024]. Similar to PROP1, EF1 alloca-tions are known to exist for any number of agents [Lipton et al., 2004]. On the other hand, the existence or non-existence of EFx allocations has not been proven in general, and it is one of the main open problems in fair division.

Web8 de set. de 2024 · One motivation for our paper is recent work by Benabbou et al. on promoting diversity in assignment problems through efficient, EF1 allocations of items to groups in a population.

WebFinally, we tracked the number of instances that had solutions that admitted either an EF or PROP allocation. Of the 900 instances we generated, only 11.2% admitted an EF solution while 71.3% admitted a PROP solution. Whereas, when looking at the EF1/PROP1 relaxations, that number is 100% for both since we know these allocations always exist. Web11 de jun. de 2024 · An allocation is said to be fair if it is envy-free up to one good (EF1), which means that each agent prefers its own bundle over the bundle of any other agent up to the removal of one good. In...
WebThe above example shows that EF1, on its own, is too coarse to distinguish between allocations that remove a large number of goods (such as the one with circled entries) and those that remove only a few (such as the one with underlined entries, which, in fact, is envy-free). This drawback highlights Webof MMA, it potentially has better egalitarian guarantee than EF1 allocations. By definition, an MMA1 allocationA guarantees that for each agent i and her favorite item e ∈A−i (suppose k), vi (Ai)is at least as large as the worst bundle in any n−1 -partition of A−i \{e}. However, if is EF1, it means there exists an (n −1)-
