Efficient algorithms to compute compressed longest common substrings and compressed palindromes

This paper studies two problems on compressed strings described in terms of straight line programs (SLPs). One is to compute the length of the longest common substring of two given SLP-compressed strings, and the other is to compute all palindromes of a given SLPcompressed string. In order to solve these problems efficiently (in polynomial time w.r.t. the compressed size) decompression is never...

Computing Longest Common Substring and All Palindromes from Compressed Strings

Heaviest Induced Ancestors and Longest Common Substrings

Suppose we have two trees on the same set of leaves, in which nodes are weighted such that children are heavier than their parents. We say a node from the first tree and a node from the second tree are induced together if they have a common leaf descendant. In this paper we describe data structures that efficiently support the following heaviest-induced-ancestor query: given a node from the fir...

Efficient algorithms for the longest common subsequence in $k$-length substrings

Finding the longest common subsequence in k-length substrings (LCSk) is a recently proposed problem motivated by computational biology. This is a generalization of the well-known LCS problem in which matching symbols from two sequences A and B are replaced with matching non-overlapping substrings of length k from A and B. We propose several algorithms for LCSk, being non-trivial incarnations of...

Finding Characteristic Substrings from Compressed Texts

Text mining from large scaled data is of great importance in computer science. In this paper, we consider fundamental problems on text mining from compressed strings, i.e., computing a longest repeating substring, longest non-overlapping repeating substring, most frequent substring, and most frequent non-overlapping substring from a given compressed string. Also, we tackle the following novel p...
