Envy-freeness up to one item
WebAverage envy-freeness provides a reasonable comparison between agents based on the items they receive and reflects their entitlements. We study the complexity of finding AEF and its relaxation, average envy-freeness up to one item (AEF-1). While deciding if an AEF allocation exists is NP-complete, an AEF-1 allocation is guaranteed to exist and ... Webas “envy-freeness up to one item” (EF1) and “proportionality up to one item” (PROP1) need to be generalized appropriately. • We show that the round-robin sequential allocation algorithm that returns an EF1 allo-cation in the case of goods does not work in general.
