Theory of Computation (Automata)
Which of the following best describes DFA-NFA equivalence?
Difficulty: Hard
About this MCQ
This Hard Theory of Computation (Automata) question asks: Which of the following best describes DFA-NFA equivalence? The correct choice is D. The concept where a DFA and an NFA are considered equivalent because they recognize exactly the same class of languages.. Read the options below, commit to one, then use the explanation to see why that choice holds and why the others do not.
Theory of Computation (Automata) items like this one are written for Pakistan exams such as CSS, FPSC, PPSC, and NTS. The difficulty label is a hint about how much of the topic the stem assumes, not a score. Tags and exam names, when they are present, tell you where else the same idea is tested. Previous and next links stay in Theory of Computation (Automata) so you can continue the subject. Related questions point at nearby stems if you want another angle on the same idea.
Treat the explanation as part of the question, not a footnote. If you missed it, reread the stem against the correct option before you open the next Theory of Computation (Automata) item. A timed quiz is the same pool with a clock and a score. A past paper is a full sitting rather than this single question.
- A. A finite-state machine whose output values are determined solely by its current state.
Why not A: “A finite-state machine whose output values are determined solely by its current state.” does not fit this question. The answer is The concept where a DFA and an NFA are considered equivalent because they recognize exactly the same class of languages..
- B. A transition in a non-deterministic automaton that occurs without consuming any input symbol.
Why not B: “A transition in a non-deterministic automaton that occurs without consuming any input symbol.” does not fit this question. The answer is The concept where a DFA and an NFA are considered equivalent because they recognize exactly the same class of languages..
- C. The process of reducing a deterministic finite automaton to the smallest possible number of states while preserving its language.
Why not C: “The process of reducing a deterministic finite automaton to the smallest possible number of states while preserving its language.” does not fit this question. The answer is The concept where a DFA and an NFA are considered equivalent because they recognize exactly the same class of languages..
- D. The concept where a DFA and an NFA are considered equivalent because they recognize exactly the same class of languages. ✓
Correct answer
D. The concept where a DFA and an NFA are considered equivalent because they recognize exactly the same class of languages.
Explanation
The concept where a DFA and an NFA are considered equivalent because they recognize exactly the same class of languages is the term that matches Which of the following best describes DFA-NFA equivalence option D Option A A finite-state machine whose output values are determined solely by its current state does not fit this question Option B A transition in a non-deterministic automaton that occurs without consuming any input symbol does not fit this question Option C The process of reducing a deterministic finite automaton to the smallest possible number of states while preserving its language does not fit this question For this Theory of Computation Automata question the accepted.
