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...

字符串匹配算法(String matching algorithm),字符串匹配算法(String matching algorithm),字符串匹配算法(String,matching,algorithm)
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 compute deterministic finite automata, which can be expensive to build, but are usually efficient ...
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,..
In a network intrusion detection system, the original AC algorithm adopts oncway matching. I}he comparing time will increase as the number of samples increases. This paper presented an efficient multi-pattern matching algorithm,a bi-directional fast string matching algorithm. The algorithm uses ...
[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。
