Efx exists for three agents
WebFeb 21, 2024 · The current state of the art is that no setting where EFX allocations are impossible is known, and EFX is known to exist for ($i$) agents with identical valuations, ($ii$) 2 agents,... WebJun 7, 2024 · In this paper, we sketch the proof of existence of “almost” EFX allocations and the existence of EFX allocations when there are only three agents. In the end, we reduce the problem of finding improved guarantees on EFX allocations to a problem in zero sum extremal combinatorics.

Unfortunately, starting from three agents, even for the well studied class of additive valuations, it is open whether EFX allocations exist.
WebApr 30, 2024 · It is shown that an EFX allocation always exists when all agents have one of two general valuations or when the number of items is at most n + 3, and new techniques are developed and some results of additive valuations to generalValuations on the existence of EFX allocations are extended. Expand. 13. PDF. WebMay 30, 2024 · In this paper, we show constructively that an EFX allocation always exists for three agents. Furthermore, we falsify the conjecture by Caragiannis et al. by showing an instance with three agents for which there is a partial EFX allocation (some items are not allocated) with higher Nash welfare than that of any complete EFX allocation. ...
