Tight bound for the number of distinct palindromes in a tree

P Gawrychowski, T Kociumaka, W Rytter… - … Symposium on String …, 2015 - Springer
For an undirected tree with n 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 O (n …

String covers of a tree

J Radoszewski, W Rytter, J Straszyński… - String Processing and …, 2021 - Springer
We consider covering labeled trees by a collection of paths with the same string label, called
a (string) cover of a tree. We show how to compute all covers of a directed (rooted) labeled …

Computing palindromes on a trie in linear time

T Mieno, M Funakoshi, S Inenaga - arXiv preprint arXiv:2211.03995, 2022 - arxiv.org
A trie $\mathcal {T} $ is a rooted tree such that each edge is labeled by a single character
from the alphabet, and the labels of out-going edges from the same node are mutually …

Efficiently computing runs on a trie

R Sugahara, Y Nakashima, S Inenaga, H Bannai… - Theoretical Computer …, 2021 - Elsevier
A maximal repetition, or run, in a string, is a maximal periodic substring whose smallest
period is at most half the length of the substring. In this paper, we consider runs that …

Computing palindromes and suffix trees of dynamic trees

M Funakoshi, T Mieno, Y Nakashima, S Inenaga… - 2024 - researchsquare.com
We consider the problems of computing maximal palindromes and distinct palindromes in
an edge-labeled rooted tree where each edge is labeled by a single character. Such a tree …

Double-Ended Palindromic Trees: A Linear-Time Data Structure and Its Applications

Q Wang, M Yang, X Zhu - arXiv preprint arXiv:2210.02292, 2022 - arxiv.org
The palindromic tree (aka eertree) is a linear-size data structure that provides access to all
palindromic substrings of a string. In this paper, we propose a generalized version of …

String Covers of a Tree Revisited

Ł Kondraciuk - International Symposium on String Processing and …, 2023 - Springer
We consider covering labeled trees with a collection of paths with the same string label,
called a (string) cover of a tree. This problem was originated by Radoszewski et al.(SPIRE …
