Fast 2-approximate all-pairs shortest paths

M Dory, S Forster, Y Kirkpatrick, Y Nazari… - Proceedings of the 2024 …, 2024 - SIAM
In this paper, we revisit the classic approximate All-Pairs Shortest Paths (APSP) problem in
undirected graphs. For unweighted graphs, we provide an algorithm for 2-approximate …

Faster Approximate All Pairs Shortest Paths

B Saha, C Ye - Proceedings of the 2024 Annual ACM-SIAM …, 2024 - SIAM
The all pairs shortest path problem (APSP) is one of the foundational problems in computer
science. For weighted dense graphs on n vertices, no truly sub-cubic algorithms exist to …

Fully polynomial-time algorithms parameterized by vertex integrity using fast matrix multiplication

M Bentert, K Heeger, T Koana - arXiv preprint arXiv:2403.01839, 2024 - arxiv.org
We study the computational complexity of several polynomial-time-solvable graph problems
parameterized by vertex integrity, a measure of a graph's vulnerability to vertex removal in …

New algorithms for all pairs approximate shortest paths

L Roditty - Proceedings of the 55th Annual ACM Symposium on …, 2023 - dl.acm.org
Let G=(V, E) be an unweighted undirected graph with n vertices and m edges. Dor, Halperin,
and Zwick [FOCS 1996, SICOMP 2000] presented an (min {n 3/2 m 1/2, n 7/3})-time …

New tradeoffs for decremental approximate all-pairs shortest paths

M Dory, S Forster, Y Nazari, T de Vos - arXiv preprint arXiv:2211.01152, 2022 - arxiv.org
We provide new tradeoffs between approximation and running time for the decremental all-
pairs shortest paths (APSP) problem. For undirected graphs with $ m $ edges and $ n …
