WebFinite Automata with Null Moves (NFA-ε) A Finite Automaton with null moves (FA-ε) does transit not only after giving input from the alphabet set but also without any input symbol. This transition without input is called a null move. An NFA-ε is represented formally by a 5-tuple (Q, ∑, δ, q 0, F), consisting of. Q − a finite set of states WebTOC: Epsilon NFAThis lecture gives the concept of Epsilon NFA and how it is defined and how is it different from the normal NFA.Contribute: http://www.nesoac...
