Webbregular expression. 1 From NFA to regular expression 1.1 NFA— A Generalized NFA Consider an NFA N where we allowed to write any regu-lar expression on the edges, and not only just symbols. The automata is allowed to travel on an edge, if it can matches a preﬁx of the unread input, to the regular expression writ-ten on the edge. WebbThe easiest one is the "state removal technique." You remove a state and replace all the edges between states that were connected to the removed state with edges labeled with regular expressions. As you reduce in this way you eventually get to a regular expression for the whole DFA. (Note that Figure 4 in the paper I linked is not quite right. ipl 22 match
