3.6 - Equivalence of NFAs and DFAs

Learning

Practice Questions

Test your understanding with targeted questions related to the topic.

Question 1

Easy

Define a Deterministic Finite Automaton (DFA).

πŸ’‘ Hint: Remember how DFAs operate uniquely for each state.

Question 2

Easy

What is the significance of Ξ΅-transitions in an NFA?

πŸ’‘ Hint: Think about how this adds flexibility.

Question 1

What is the key characteristic of a Deterministic Finite Automaton (DFA)?

  • Has multiple transitions for each input
  • Has exactly one transition for each input
  • Can change states without consuming input

πŸ’‘ Hint: Recall the distinction between deterministic and non-deterministic.

Question 2

True or False: NFAs can be converted to equivalent DFAs.

  • True
  • False

πŸ’‘ Hint: Consider the implications of the Equivalence Theorem.

Challenge Problems

Push your limits with challenges.

Question 1

Design an NFA that recognizes the language of all strings over {0,1} with at least one '01' substring. Convert this NFA to a DFA using the Subset Construction Algorithm and show step-by-step state transitions.

πŸ’‘ Hint: Outline the NFA first clearly, then define transitions capturing Ξ΅-closures.

Question 2

Discuss the implications of using NFAs versus DFAs in a real-world application such as a compiler. Which might be better in which scenarios? Provide examples.

πŸ’‘ Hint: Consider the different stages of compiler design when making your choice.
