Web6 de dez. de 2024 · In this paper, we resolve the price of two well-studied fairness notions in the context of indivisible goods: envy-freeness up to one good ( \textsc {EF1} ) and approximate maximin share ( \textsc {MMS} ). For both \textsc {EF1} and we show, via different techniques, that the price of fairness is O (\sqrt {n}), where n is the number of … 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.
