Dynamic algorithms for maximum matching size

S Behnezhad - Proceedings of the 2023 Annual ACM-SIAM …, 2023 - SIAM
We study fully dynamic algorithms for maximum matching. This is a well-studied problem,
known to admit several update-time/approximation trade-offs. For instance, it is known how …

the problem of computing an optimal coloring, or even approximating it to within n1-ε for any …

Beating the folklore algorithm for dynamic matching

M Roghani, A Saberi, D Wajc - arxiv preprint arxiv:2106.10321, 2021 - arxiv.org
The maximum matching problem in dynamic graphs subject to edge updates (insertions and
deletions) has received much attention over the last few years; a multitude of …

New trade-offs for fully dynamic matching via hierarchical EDCS

S Behnezhad, S Khanna - Proceedings of the 2022 Annual ACM-SIAM …, 2022 - SIAM
We study the maximum matching problem in fully dynamic graphs: a graph is undergoing
both edge insertions and deletions, and the goal is to efficiently maintain a large matching …

Maintaining an EDCS in general graphs: Simpler, density-sensitive and with worst-case time bounds
