-time Algorithm for Bounded Tree Edit Distance

Debarati Das, Jacob Gilbert, MohammadTaghi Hajiaghayi +3

Computing the edit distance of two strings is one of the most basic problems in computer science and combinatorial optimization. Tree edit distance is a natural generalization of e…

Faster Pattern Matching under Edit Distance

Panagiotis Charalampopoulos, Tomasz Kociumaka, Philip Wellnitz

We consider the approximate pattern matching problem under the edit distance. Given a text of length , a pattern of length , and a threshold , the task is to find…

Computing Longest (Common) Lyndon Subsequences

Hideo Bannai, Tomohiro I, Tomasz Kociumaka +2

Given a string with length whose characters are drawn from an ordered alphabet of size , its longest Lyndon subsequence is a longest subsequence of that is a Lyndon…

Small space and streaming pattern matching with k edits

Tomasz Kociumaka, Ely Porat, Tatiana Starikovskaya

In this work, we revisit the fundamental and well-studied problem of approximate pattern matching under edit distance. Given an integer , a pattern of length , and a text…

Improved Dynamic Algorithms for Longest Increasing Subsequence

Tomasz Kociumaka, Saeed Seddighin

We study dynamic algorithms for the longest increasing subsequence (\textsf{LIS}) problem. A dynamic \textsf{LIS} algorithm maintains a sequence subject to operations of the follow…

Tight Bound for the Number of Distinct Palindromes in a Tree

Paweł Gawrychowski, Tomasz Kociumaka, Wojciech Rytter +1

For an undirected tree with edges labelled by single letters, we consider its substrings, which are labels of the simple paths between pairs of nodes. We prove that there are $…
