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 …

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 …
