Abstract

Approximate pattern matching plays an important role in various applications, such as bioinformatics, computer-aided music analysis and computer vision. We focus on (δ, γ)-matching. Given a text T of length n, a pattern P of length m,and two parameters δ and γ, the aim is to find all the substring T[i, i+m–1] such that (a) ∀ 1 ≤ jm, |T[i+j–1] – P[j]| ≤ δ (δ-matching) , and (b) ∑1 ≤ j ≤ m |T[i+j–1] – P[j]| ≤ γ (γ-matching). In this paper we consider three variations of (δ, γ)-matching: amplified matching, transposition-invariant matching, and amplified transposition-invariant matching. For each problem we propose a simple and efficient algorithm which is easy to implement.
