Output-sensitive approximate counting via a measure-bounded hyperedge oracle, or: How asymmetry helps estimate -clique counts faster
Keren Censor-Hillel, Tomer Even, Virginia Vassilevska Williams
Dell, Lapinskas and Meeks [DLM SICOMP 2022] presented a general reduction from approximate counting to decision for a class of fine-grained problems that can be viewed as hyperedge…
Faster Weighted and Unweighted Tree Edit Distance and APSP Equivalence
Jakob Nogler, Adam Polak, Barna Saha +3
The tree edit distance (TED) between two rooted ordered trees with nodes labeled from an alphabet is the minimum cost of transforming one tree into the other by a sequence…
Fredman's Trick Meets Dominance Product: Fine-Grained Complexity of Unweighted APSP, 3SUM Counting, and More
Timothy M. Chan, Virginia Vassilevska Williams, Yinzhan Xu
In this paper we carefully combine Fredman's trick [SICOMP'76] and Matoušek's approach for dominance product [IPL'91] to obtain powerful results in fine-grained complexity: - Under…
Subtree Isomorphism Revisited
Amir Abboud, Arturs Backurs, Thomas Dueholm Hansen +2
The Subtree Isomorphism problem asks whether a given tree is contained in another given tree. The problem is of fundamental importance and has been studied since the 1960s. For som…
