How to Walk a Dog in Parallel: On Parallel Computation of the Discrete Frechet Distance

Leonid Barenboim, Arnold Filtser, Omrit Filtser +1

The Fréchet distance (also known as the dog-leash distance) is a well-studied and prevalent distance measure for polygonal curves. In this paper we present parallel algorithms for…

Near-Resolution of the Tradeoff Conjecture in Distributed Proof Labeling Schemes

Arnold Filtser, Orr Fischer

In the -Proof Labeling Scheme model (-PLS model), our goal is to certify that a network of nodes satisfies a given property . A prover assigns a label to each node, and ea…

The Task Completion Problem and its Application to Crash-Resilient Computation

Orr Fischer, Ran Gelles

We study the Task Completion problem, in which abstract tasks must be completed by a network of crash-prone nodes, where up to nodes may crash for some constant .…

Pointer Chasing with Unlimited Interaction

Orr Fischer, Rotem Oshman, Adi Rosen +1

Pointer-chasing is a central problem in two-party communication complexity: given input size and a parameter , the two players Alice and Bob are given functions $N_A, N_B: […

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…

All-to-All Communication with Mobile Edge Adversary: Almost Linearly More Faults, For Free

Orr Fischer, Merav Parter

Resilient computation in all-to-all-communication models has attracted tremendous attention over the years. Most of these works assume the classical faulty model which restricts th…

Distributed CONGEST Algorithms against Mobile Adversaries

Orr Fischer, Merav Parter

In their seminal PODC 1991 paper, Ostrovsky and Yung introduced the study of distributed computation in the presence of mobile adversaries which can dynamically appear throughout t…

Massively Parallel Computation in a Heterogeneous Regime

Orr Fischer, Adi Horowitz, Rotem Oshman

Massively-parallel graph algorithms have received extensive attention over the past decade, with research focusing on three memory regimes: the superlinear regime, the near-linear…

Tree Learning: Optimal Algorithms and Sample Complexity

Dmitrii Avdiukhin, Grigory Yaroslavtsev, Danny Vainstein +3

We study the problem of learning a hierarchical tree representation of data from labeled samples, taken from an arbitrary (and possibly adversarial) distribution. Consider a collec…

Fast Distributed Algorithms for Girth, Cycles and Small Subgraphs

Keren Censor-Hillel, Orr Fischer, Tzlil Gonen +3

In this paper we give fast distributed graph algorithms for detecting and listing small subgraphs, and for computing or approximating the girth. Our algorithms improve upon the sta…

Superlinear Lower Bounds for Distributed Subgraph Detection

Orr Fischer, Tzlil Gonen, Rotem Oshman

In the distributed subgraph-freeness problem, we are given a graph , and asked to determine whether the network graph contains as a subgraph or not. Subgraph-freeness is an…

On The Multiparty Communication Complexity of Testing Triangle-Freeness

Orr Fischer, Shay Gershtein, Rotem Oshman

In this paper we initiate the study of property testing in simultaneous and non-simultaneous multi-party communication complexity, focusing on testing triangle-freeness in graphs.…

Distributed Property Testing for Subgraph-Freeness Revisited

Orr Fischer, Tzlil Gonen, Rotem Oshman

In the subgraph-freeness problem, we are given a constant-size graph , and wish to determine whether the network contains as a subgraph or not. The \emph{property-testing} r…

A Lower Bound for the Distributed Lovász Local Lemma

Sebastian Brandt, Orr Fischer, Juho Hirvonen +5

We show that any randomised Monte Carlo distributed algorithm for the Lovász local lemma requires communication rounds, assuming that it finds a correct assignment…
