Envy-freeness up to one item: Shall we add or remove resources?

no code implementations • 19 Jun 2020 • Martin Aleksandrov

We consider a fair division model in which agents have general valuations for bundles of indivisible items.

Jealousy-freeness and other common properties in Fair Division of Mixed Manna

no code implementations • 23 Apr 2020 • Martin Aleksandrov

We consider a fair division setting where indivisible items are allocated to agents.

Greedy Algorithms for Fair Division of Mixed Manna

no code implementations • 25 Nov 2019 • Martin Aleksandrov, Toby Walsh

For example, we show that maximizing the Nash welfare with mixed manna (or minimizing the disutility Nash welfare) does not ensure an EF1 allocation whereas with goods and the Nash welfare it does.
