Engage in quick quizzes to reinforce what you've learned and check your comprehension.

Question 1

What is a determining factor for a Turing Machine to halt?

  • A finite number of states
  • A finite input length
  • Both A and B
  • Neither A nor B

πŸ’‘ Hint: Think about the components of the Turing Machine and their characteristics.

Question 2

True or False: Every decidable language is also Turing-recognizable.

  • True
  • False

πŸ’‘ Hint: Consider the definitions of decidability and Turing-recognizability.

Challenge Problems

Push your limits with challenges.

Question 1

Design a Turing Machine for a language that accepts strings consisting of an equal number of 'a's and 'b's.

πŸ’‘ Hint: Focus on how you would structurally implement the TM's transitions.

Question 2

Explain how the properties of non-deterministic Turing Machines change the perspective on language acceptance.

πŸ’‘ Hint: Reflect on how exploration of multiple paths may help in certain scenarios versus traditional determinism.
