A graph-theoretic model to solve the approximate string matching problem allowing for translocations

Abstract

In this paper, we study the approximate string matching problem under a string distance whose edit operations are translocations of equal length factors. We extend a graph-theoretic approach proposed by Rahman and Illiopoulos (2008) to model our problem. In the sequel, we devise efficient algorithms based on this model to solve a number of variants of the string matching problem with translocations.
