Nfa

XFA library implements an API that can be used to create NFA (either programmatically or from regular expressions) and to convert them in the minimal equivalent DFA. XFA library requires an ANSI C compiler, and this makes it portable virtually over every system. The complexity of the graphs... Platforms: *nix

dk.brics.automaton project is a Java package that contains a DFA/NFA (finite-state automata) implementation with Unicode alphabet (UTF16) and support for the standard regular expression operations (concatenation, union, Kleene star) and a number of non-standard ones (intersection, complement,...

FLAT::Legacy::FA::RE is a regular expression base class. SYNOPSIS use FLAT::Legacy::FA::RE; use FLAT::Legacy::FA::NFA; my $re = RE->new(); $re->set_re(a|b|(hi)*); my $nfa = $re->to_nfa(); print $nfa->info(); # see stuff on NFA my $dfa = $nfa->to_dfa(); print $dfa->info(); # see stuff...

RegexVisualizer is a free Mac OS X app which will convert a formal regular expression to an ?zA*-NFA and visualizes it in the form of a transition table. RegexVisualizer uses the algorithm described in section 3.2.3 of "Introduction to Automata Theory, Languages & Computation" to create the... Platforms: Mac

FSA::Rules is a Perl module to build simple rules-based state machines in Perl. Synopsis my $fsa = FSA::Rules->new( ping => { do => sub { print "ping!n"; my $state = shift; $state->result(pong); $state->machine->{count}++; }, rules => [ game_over => sub { shift->machine->{count} >=...

The XFA library is a Finite Automata (FA) library to handle tasks like building (programmatically or from regular expressions), converting NFA (Non-deterministic FA) to DFA (Deterministic FA) and reducing FA graphs.The library relies only on the availability of an ANSI C compiler, and in this way...
