Time and Space Optimal Exact Majority Population Protocols

Leszek Gąsieniec, Grzegorz Stachowiak, Przemysław Uznański

In this paper we study population protocols governed by the {\em random scheduler}, which uniformly at random selects pairwise interactions between agents. The main result of t…

Pattern Matching in a Stream

Tatiana Starikovskaya, Michal Svagerka, Przemysław Uznański

We consider the problem of computing distance between a pattern of length and all -length subwords of a text in the streaming model. In the streaming setting, only the Hammi…

RLE edit distance in near optimal time

Raphaël Clifford, Paweł Gawrychowski, Tomasz Kociumaka +2

We show that the edit distance between two run-length encoded strings of compressed lengths and respectively, can be computed in time. This improv…

Hardness of Exact Distance Queries in Sparse Graphs Through Hub Labeling

Adrian Kosowski, Przemysław Uznański, Laurent Viennot

A distance labeling scheme is an assignment of bit-labels to the vertices of an undirected, unweighted graph such that the distance between any pair of vertices can be decoded sole…

Approximating Approximate Pattern Matching

Jan Studený, Przemysław Uznański

Given a text of length and a pattern of length , the approximate pattern matching problem asks for computation of a particular \emph{distance} function between a…

Faster Algorithms for All-Pairs Bounded Min-Cuts

Amir Abboud, Loukas Georgiadis, Giuseppe F. Italiano +5

The All-Pairs Min-Cut problem (aka All-Pairs Max-Flow) asks to compute a minimum - cut (or just its value) for all pairs of vertices . We study this problem in directed…
