the product of utilities—is known to provide outstanding fairness guarantees when allocating …

Finding fair and efficient allocations

S Barman, SK Krishnamurthy, R Vaish - … of the 2018 ACM Conference on …, 2018 - dl.acm.org
We study the problem of allocating a set of indivisible goods among a set of agents in a fair
and efficient manner. An allocation is said to be fair if it is envy-free up to one good (EF1) …

EFX exists for three agents

BR Chaudhury, J Garg, K Mehlhorn - Journal of the ACM, 2024 - dl.acm.org
We study the problem of distributing a set of indivisible goods among agents with additive
valuations in a fair manner. The fairness notion under consideration is envy-freeness up to …

A little charity guarantees almost envy-freeness

BR Chaudhury, T Kavitha, K Mehlhorn… - SIAM Journal on …, 2021 - SIAM
The fair division of indivisible goods is a very well-studied problem. The goal of this problem
is to distribute m goods to n agents in a “fair” manner, where every agent has a valuation for …

Fair allocation of indivisible goods: Improvements and generalizations

We study the problem of fair allocation for indivisible goods. We use the maxmin share
paradigm introduced by Budish~\citeBudish: first as a measure for fairness.\procacciafirst …

Envy-freeness up to any item with high Nash welfare: The virtue of donating items

I Caragiannis, N Gravin, X Huang - … of the 2019 ACM Conference on …, 2019 - dl.acm.org
Several fairness concepts have been proposed recently in attempts to approximate envy-
freeness in settings with indivisible goods. Among them, the concept of envy-freeness up to …

Log-concave polynomials, entropy, and a deterministic approximation algorithm for counting bases of matroids

N Anari, SO Gharan, C Vinzant - 2018 IEEE 59th Annual …, 2018 - ieeexplore.ieee.org
We give a deterministic polynomial time 2^ O (r)-approximation algorithm for the number of
bases of a given matroid of rank r and the number of common bases of any two matroids of …

Competitive division of a mixed manna

A Bogomolnaia, H Moulin, F Sandomirskiy… - …, 2017 - Wiley Online Library
A mixed manna contains goods (that everyone likes) and bads (that everyone dislikes), as
well as items that are goods to some agents, but bads or satiated to others. If all items are …

Online nash social welfare maximization with predictions

We consider the problem of allocating a set of divisible goods to N agents in an online
manner, aiming to maximize the Nash social welfare, a widely studied objective which …

Approximating the Nash social welfare with indivisible items

R Cole, V Gkatzelis - Proceedings of the forty-seventh annual ACM …, 2015 - dl.acm.org
We study the problem of allocating a set of indivisible items among agents with additive
valuations, with the goal of maximizing the geometric mean of the agents' valuations, ie, the …
