Explain the ε\varepsilonε-closure of states on an ε\varepsilonε-NFA with suitable examples.

ε-closure of a state q is the set of all states that can be reached from state q by following zero or more ε (epsilon) transitions, without consuming any input symbol. Formally: ε-closure(q) = { p ∈ Q p is reachable from q using only ε-transitions } Key points: - Every state is always in its own ...
