Large cliques and large independent sets: can they coexist?
Uriel Feige, Ilia Pauzner
For a graph and a parameter , we call a vertex -enabling if it belongs both to a clique of size and to an independent set of size , and we call it -excluding ot…
The residual maximin share
Uriel Feige
We consider fair allocations of indivisible goods to agents with general monotone valuations. We observe that it is useful to introduce a new share-based fairness notion, the {\em…
From multi-allocations to allocations, with subadditive valuations
Uriel Feige
We consider the problem of fair allocation of indivisible items to agents with monotone subadditive valuations. For integer , a -multi-allocation is an allocati…
Upper bounds on the theta function of random graphs
Uriel Feige, Vadim Grinberg
The theta function of Lovasz is a graph parameter that can be computed up to arbitrary precision in polynomial time. It plays a key role in algorithms that approximate graph parame…
Fair allocations with subadditive and XOS valuations
Uriel Feige, Vadim Grinberg
We consider the problem of fair allocation of indivisible goods to agents with either subadditive or XOS valuations, in the arbitrary entitlement case. As fairness notions,…
Concentration and maximin fair allocations for subadditive valuations
Uriel Feige, Shengyu Huang
We consider fair allocation of indivisible items to agents of equal entitlements, with submodular valuation functions. Previously, Seddighin and Seddighin [{\em Artificial…
