Question

Select a states that is not q2 from the GNFA to delete. Then, create a new GNFA for the deleted state that is equivalent to M but does not have the selected state.

Expert Solution

Step 1

GNFA:

In the theory of computation, a generalized nondeterministic finite automaton (GNFA), also known as an expression automaton or a generalized nondeterministic finite state machine, is a variation of a nondeterministic finite automaton (NFA) where each transition is labelled with any regular expression.

A DFA can be converted to an equivalent GNFA by

Adding a new start state with an ε transition to the old start state.
Adding a new accepting state and adding ε transitions from all old accepting states to the new one.
Definining the transition function δ^' for the GNFA in terms of the transition function δ for the DFA by
δ^'(q_i, q_j) = a if and only if δ(q_i, a) = q_j
