The Complexity of Dynamic LZ77 is
Itai Boneh, Shay Golan, Matan Kraus
The Lempel-Ziv 77 (LZ77) factorization is a fundamental compression scheme widely used in text processing and data compression. In this work, we investigate the time complexity of…
Deterministic Longest Common Subsequence Approximation in Near-Linear Time
Itai Boneh, Shay Golan, Matan Kraus
We provide a deterministic algorithm that outputs an -approximation for the Longest Common Subsequence (LCS) of two input sequences of length in near-linear…
String Problems in the Congested Clique Model
Shay Golan, Matan Kraus
In this paper we present algorithms for several string problems in the Congested Clique model. In the Congested Clique model, nodes (computers) are used to solve some problem.…
Ãptimal Fault-Tolerant Labeling for Reachability and Approximate Distances in Directed Planar Graphs
Itai Boneh, Shiri Chechik, Shay Golan +2
We present a labeling scheme that assigns labels of size to the vertices of a directed weighted planar graph , such that for any fixed from the lab…
Faster Construction of a Planar Distance Oracle with Ã(1) Query Time
Itai Boneh, Shay Golan, Shay Mozes +2
We show how to preprocess a weighted undirected -vertex planar graph in time, such that the distance between any pair of vertices can then be reported in $\t…
Expected Density of Random Minimizers
Shay Golan, Arseny M. Shur
Minimizer schemes, or just minimizers, are a very important computational primitive in sampling and sketching biological strings. Assuming a fixed alphabet of size , a minimize…
