Is there a good library for converting Regular Expressions into NFAs? I see lots of academic papers on the subject, which are helpful, but not much in the way of working code. My question is due partially to curiosity, and partially to an actual need to speed up regular expression matching on a production system I'm working on. Althou...
Does anybody know if Python (any version) used NFAs (Non-Deterministic Finite Automata) to evaluate regular expressions or does it use some other mechanism? Please provide links/reference if available. ...
Can there be an NFA that decides on real numbers ? ...
Hi Guys... Hope you help me with this one.... I have a main question which is ''how to judge whether a regular expression will be accepted by NFA and/or DFA? For eg. My question says that which of the regular expressions are equivalent? explain... 1.(a+b)*b(a+b)*b(a+b)* 2.a*ba*ba* 3.a*ba*b(a+b)* do we have to draw the NFA and DFA an...
Could you recommend an open source library written in F# which provides generic types for FA construction and basic algorithms (NFA to DFA transformation, FA minimization ...)? ...
I'm currently working on a scanner generator. The generator already works fine. But when using character classes the algorithm gets very slow. The scanner generator produces a scanner for UTF8 encoded files. The full range of characters (0x000000 to 0x10ffff) should be supported. If I use large character sets, like the any operator '....
I'm thinking so, because the upper bound would be the 2^n, and given that these are both finite machines, the intersection for both the n-state NFA and the DFA with 2^n or less states will be valid. Am I wrong here? ...
Do there exists any Standard Syntax for Describing the Transition Table for an NFA or DFA ? ...
Look for a non-technical explanation of the difference between DFA vs NFA engines based on their capabilities and limitations. Thanks! ...
Good night, Let's suppose I have a class which implements a NFA/DFA whose transitions are stored in a .NET Dictionary structure, and which takes an input word and recognizes a set of words derivable in some way from the input. Furthermore, let's suppose that the automaton is a generic template that can be applied to different words of t...
Good night, Does anyone know of any good NFA and DFA implementation in C#, possibly implementing as well conversions between both? What I would like would be to be able to construct a NFA and then convert it automatically to a DFA, but without having to write my own code which would take a very long time. There is this Python code which...
