字符串精确匹配问题的综合实验评价

The Exact String Matching Problem: a Comprehensive Experimental Evaluation

Simone Faro, Thierry Lecroq

摘要:

本文讨论了在线精确字符串匹配问题,即在文本t中找到给定模式p的所有出现。它是计算机科学中广泛研究的问题,主要是由于其直接应用于文本、图像和信号处理、语音分析和识别、数据压缩、信息检索、计算生物学和化学等不同领域。自1970年以来,人们提出了80多种字符串匹配算法,其中50%以上是在最近十年内提出的。在本说明中,我们提出了一个全面的列表,所有字符串匹配算法,并提出实验结果,以比较它们从实用的角度来看。从我们的实验评估结果表明,算法的性能是相当不同的字母大小和模式长度。

英文摘要:

This paper 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, 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.
