The automaton which allows transformation to a new state without consuming any input symbols:
NFA-l or e-NFA is an extension of Non deterministic Finite Automata which are usually called NFA with epsilon moves or lambda transitions.
An epsilon move is a transition from one state to another that doesn’t require any specific condition.
The __________ of a set of states, P, of an NFA is defined as the set of states reachable from any state in P following e-transitions.
: The e-closure of a set of states, P, of an NFAis defined as the set of states reachable from any state in P following e-transitions.
he e-NFA recognizable languages are not closed under :
The languages which are recognized by an epsilon Non deterministic automata are closed under the following operations:
f) Kleene closure
Is the language preserved in all the steps while eliminating epsilon transitions from a NFA?
Yes, the language is preserved during the dteps of construction: L(N)=L(N1)=L(N2)=L(3).
An e-NFA is ___________ in representation.
Correct Answer :- A
Explanation : An e-NFA consist of 5 tuples: A=(Q, S, d, q0, F)
Note: e is never a member of SAn e-NFA consist of 5 tuples: A=(Q, S, d, q0, F)
Note: e is never a member of S.
State true or false:Statement: Both NFA and e-NFA recognize exactly the same languages.
e-NFA do come up with a convenient feature but nothing new.They do not extend the class of languages that can be represented.
