Witness-Sensitive Detection of Induced Diamonds
Keren Censor-Hillel, Tomer Even, Virginia Vasillevska Williams +1
We provide a fast \emph{witness-sensitive} algorithm for detecting an induced diamond (a minus an edge) in an -vertex graph containing induced diamonds. Our algorithm…

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…

When MIS and Maximal Matching are Easy in the Congested Clique
Keren Censor-Hillel, Tomer Even, Maxime Flin +1
Two of the most fundamental distributed symmetry-breaking problems are that of finding a maximal independent set (MIS) and a maximal matching (MM) in a graph. It is a major open qu…
