The exact online string matching problem: A review of the most recent results

Abstract: This article addresses the online exact string matching problem which consists in finding all occurrences of a given pattern p in a text t. It is an extensively studied problem in computer science, mainly due to its direct applications to such diverse areas as text, image and signal processing, speech analysis and recognition, information retrieval, data compression, computational biology and chemistry.In the last decade more than 50 new algorithms have been proposed for the problem, which add up to a wide set of (almost 40) algorithms presented before 2000. In this article we review the string matching algorithms presented in the last decade and present experimental results in order to bring order among the dozens of articles published in this area.

Efficient variants of the backward-oracle-matching algorithm

Abstract: In this article we present two efficient variants of the BOM string matching algorithm which are more efficient and flexible than the original algorithm. We also present bitparallel versions of them obtaining an efficient variant of the BNDM algorithm. Then we compare the newly presented algorithms with some of the most recent and effective string matching algorithms. It turns out that the new proposed variants are very flexible and achieve very good results, especially in the case of large alphabets.

The Exact String Matching Problem: a Comprehensive Experimental Evaluation

Abstract: This paper addresses the online exact string matching prob- lem which consists in finding all occurrences of a given pattern p in a text t. It is an extensively studied problem in computer science, mainly due to its direct applications to such diverse areas as text, image and signal pro- cessing, speech analysis and recognition, data compression, information retrieval, computational biology and chemistry. Since 1970 more than 80 string matching algorithms have been proposed, and more than 50% of them in the last ten years. In this note we present a comprehensive list of all string matching algorithms and present experimental results in order to compare them from a practical point of view. ?From our experimental evaluation it turns out that the performance of the algorithms are quite different for different alphabet sizes and pattern length.

Fast-search: a new efficient variant of the Boyer-Moore string matching algorithm

Abstract: We present a new variant of the Boyer-Moore string matching algorithm which, though not linear, is very fast in practice. We compare our algorithm with the Horspool, Quick Search, Tuned Boyer-Moore, and Reverse Factor algorithms, which are among the fastest string matching algorithms for practical uses. It turns out that our algorithm achieve very good results in terms of both time efficiency and number of character inspections, especially in the cases in which the patterns are very short.

I and i

Abstract: There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality. Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …
