In this study, the Wu-Manber algorithm, one of the multiple exact string matching algorithms, is improved. Although the Wu-Manber algorithm is effective, it has some limitations, such as hash collisions. In this
It returns TRUE if the first string is not found in the second string. ▪ =~ is the regular expression-matching operator. It returns TRUE if the string matches the supplied regular expression, and FALSE if it does not. s =~ [abcj+zzz is functionally equivalent to ereg(string:s, ...

Pattern matching is a very important algorithm used in many applications such as search engine and DNA analysis. They are aiming to find a pattern in a text. This paper proposes a Pattern Matching Algorithm Using Changing Consecutive Characters (PMCCC) to make the searching pro- cess of the ...
We present a new algorithm for on-line approximate string matching. The algorithm is based on the simulation of a nondeterministic finite automaton built from the pattern and using the text as input. This simulation uses bit operations on a RAM machine with word length w = Ω (log n) bits...

We consider the problem of string matching in Network Intrusion Detection Systems (NIDSes). String matching computations dominate in the overall cost of running a NIDS, despite the use of efficient general-purpose string matching algorithms. Aiming at in
The string searching or string matching problem is that of locating one string, known as a needle or a pattern, as a substring of another, longer string, known as a haystack or the text. (These terms are derived from the idiom finding a needle in a haystack.) It is precisely the funct...
Recently a new variation of approximate Boyer-Moore string matching was presented for the k -mismatch problem. The variation, called FAAST, is specifically tuned for small alphabets. We further improve this algorithm gaining speedups in both preprocessing and searching. We also present three variations...
