Distributed Stochastic Graph Algorithms
Keren Censor-Hillel, Aditi Dudeja, George Giakkoupis
We study stochastic graph optimization problems in a novel distributed setting. As in the standard centralized setting, a random subgraph of a known base graph is realize…
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…
Computing in a Faulty Congested Clique
Keren Censor-Hillel, Pedro Soto
We study a Faulty Congested Clique model, in which an adversary may fail nodes in the network throughout the computation. We show that any task of -bit input per node…
Distributed Subgraph Finding: Progress and Challenges
Keren Censor-Hillel
This is a survey of the exciting recent progress made in understanding the complexity of distributed subgraph finding problems. It overviews the results and techniques for assorted…
Two for One, One for All: Deterministic LDC-based Robust Computation in Congested Clique
Keren Censor-Hillel, Orr Fischer, Ran Gelles +1
We design a deterministic compiler that makes any computation in the Congested Clique model robust to a constant fraction of adversarial crash faults. In particular, we show…
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…
