WebWe have now finished the series concerning the basics of lexical analysis. We have defined regular expressions, the two sub-types of FAs and we have seen how we can convert between the two, as well as expressing a regular expression as both an NFA and a DFA. In the next articles, we will start talking about the basics of syntax analysis. WebDetail: This is an experiment of the principle of compilation.

An ε-NFA is like an NFA, except that we are allowed to include "epsilon transitions". In a normal NFA or DFA, every character in the string causes a single transition in the machine, and each transition in the machine "consumes" one character.
