We present a solution to the problem of regular expression searching on compressed text. The format we choose is the Ziv-Lempel family, speci cally the LZ78 and LZW variants. Give...
Directed Acyclic Word Graph (DAWG) is a space efficient data structure that supports indices of a string. Compact Directed Acyclic Word Graph (CDAWG) is a more space efficient vari...
Abstract. Compressed pattern matching is one of the most active topics in string matching. The goal is to find all occurrences of a pattern in a compressed text without decompress...
In 1995, Hannenhalli and Pevzner gave a first polynomial solution to the problem of finding the minimum number of reversals needed to sort a signed permutation.Their solution, a...
We present a solution for the following problem. Given two sequences X = x1x2 · · · xn and Y = y1y2 · · · ym, n ≤ m, find the best scoring alignment of X = Xk [i] vs Y ove...
