Further speed optimization concerning detection via search character coincidence in headers or payload of packets using wildcard Perl Compatible Regular Expressions
(PCRE)  expressions performed in GP.
We evaluated our matching approach by regular expression
sets extracted from two real-world systems named L7-Filter and Snort.
Finite automata, digraph connectivity, and regular expression
The system introduces a regular expression
search engine to reduce response time.
Dexter allows complex searches on both annotations and text, including regular expressions
and filtering by speaker characteristics.
To compile our regular expression
patterns into finite-state automata, we use flex , a standard scanner generator that does character-level regular expression
are a way of writing fuzzy queries against data sets that can be more flexible and quicker to use.
It is not possible to write a single regular expression
that returns a phrase.
First, the URL of node n3 is extracted from the link to n3, namely, 13, using the PERL regular expression
in line 11.
We use [Sigma] as a regular expression
denoting any symbol in the alphabet.
Since the FSM M' is a negation of M, all valid strings generating from regular expression
r will not arrive at the finite states and would be rejected, while all incorrect ones would be accepted in machine M'.
