字符串匹配算法(3)---String Matching Algorithm 由于有限自动机方法与KMP算法类似,并且有限自动机方法在预处理上的时间复杂度比KMP方法高,所以在本文的讨论中,暂时不讨论有限自动机方法,主要是考虑KMP算法。 KMP算法是一个非常有名的字符串匹配算法,其由Knuth,Morris和Pratt一起提出来的,预处理时间为O(m),其中m...

Aho - Corasick string matching algorithm 俗称:多模式匹配算法,它是对 Knuth - Morris - pratt algorithm (单模式匹配算法) 形成多模式匹配算法的一种改进,如果我们用单模式匹配算法实现多模式匹配算法,假如模式串有 M 个 , 则需要重复调用 M 次单模式匹配算法 ; 举个很简单的例子,假如我现在有一本特殊的字典...
A string matching algorithm returns parts of text matching a given pattern, such as a regular expression . Such algorithms have countless applications, from file editing to bioinformatics. Many algorithms computedeterministic finite automata, which can be expensive to build, but are usually efficient ...

In this paper, we present a distributed algorithm which runs on the N-cube and solves the string matching problem. A basic prefix-suffix matching technique is used as a building block in the construction of the algorithm. As opposed to the parallel algorithm so far designed on shared-memory ...
