Test: Finite Automata With Epsilon Transition - Computer Science Engineering (CSE) MCQ

The set of states which can be reached from q using ε-transitions, is called the ε-closure over state q.

It is possible to construct an NFA with ε-transitions, presence of no input symbols, and that is called NFA with ε-moves.

ε does not appears on Input tape, ε transition means a transition without scanning a symbol i.e. without moving the read head.

 The transition with ε leads to a jump but without any shift in read head. Further, the method can be called one to introduce hidden non-determinism.

The set of states which can be reached from q using ε-transitions, is called the ε-closure over state q.

The NFA which would result after eliminating ε-moves can be shown diagramatically.

Due to the presence of ε symbol, or rather an epsilon-move, the input alphabets unites with it to form a set including ε.

All the mentioned are the closure properties of ε and encircles all the elements if it satisfies the following options:
a) Every element of S ϵ Q
b) For any q ϵ ε(S), every element of δ (q, ε) is in ε(S)
c) No other element is in ε(S)

 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 doesnt require any specific condition.
