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 ...

[Algorithm] *String Matching and Hashing Link:Computer Algorithms: Rabin-Karp String Searching 为了避免挨个字符对文本和模式串进行比较,我们可以尝试一次性判断两者是否相等。 因此,我们需要一个好的哈希函数(hash function)。通过哈希函数,我们可以算出模式串的哈希值,然后将它和文本中的子串的哈希值进行比较。
Exact String Matching Algorithms String-algorithm Preliminary Definitions A string is a sequence of characters. In our model we are going to represent a string as a 0-indexed array. So a string S = ”Galois” is indeed an array [‘G’, ’a’, ’l’, ’o’, ’i’, ’s’]. The...
