Parameterized matching with mismatches
The problem of approximate parameterized string searching consists of finding, for a given text t = t1t2 . . . tn and pattern p = p1p2 . . . pm over respective alphabets Σt and Σp , the injection πi from Σp to Σt maximizing the number of matches between πi(p) and ti ti+1 . . . ti+m−1 (i = 1,2, . . . , n −m + 1). We examine the special case where both strings are run-length encoded, and further ...
متن کاملFast String Matching with Mismatches
We describe and analyze three simple and fast algorithms on the average for solving the problem of string matching with a bounded number of mismatches. These are the naive algorithm, an algorithm based on the Boyer-Moore approach, and ad-hoc deterministic nite automata searching. We include simulation results that compare these algorithms to previous works.
متن کاملOn String Matching with Mismatches
In this paper, we consider several variants of the pattern matching with mismatches problem. In particular, given a text T = t1t2 · · · tn and a pattern P = p1p2 · · · pm, we investigate the following problems: (1) pattern matching with mismatches: for every i, 1 ≤ i ≤ n −m + 1 output, the distance between P and titi+1 · · · ti+m−1; and (2) pattern matching with k mismatches: output those posit...
متن کاملOrder-Preserving Pattern Matching with k Mismatches
We study a generalization of the order-preserving pattern matching recently introduced by Kubica et al. (Inf. Process. Let., 2013) and Kim et al. (submitted to Theor. Comp. Sci.), where instead of looking for an exact copy of the pattern, we only require that the relative order between the elements is the same. In our variant, we additionally allow up to k mismatches between the pattern of leng...
متن کاملMatching with mismatches and assorted applications
This thesis consists of three parts, each of independent interest, yet tied together by the problem of matching with mismatches. In the first chapter, we present a motivated exposition of a new randomized algorithm for indexed matching with mismatches which, for constant error (substitution) rates, locates a substring of length m within a string of length n faster than existing algorithms by a ...
