What is the computational complexity of the Halting Problem?

Asked In: BPSC TRE 3.0

Options

  • A. O(1)
  • B. O(n)
  • C. Not computable
  • D. More than one of the above
  • E. None of the above

Correct Answer (Detailed Explanation is Below)

C. Not computable

Detailed Explanation

  • Halting Problem: Determines whether a given program or Turing Machine will eventually halt or run forever for a particular input.
  • Alan Turing: Proved in 1936 that the general Halting Problem is undecidable.
  • Not Computable: No algorithm can correctly solve the general Halting Problem for all possible program-input pairs.
  • Exam Point: It is an undecidable problem, not an O(1) or O(n) complexity problem.
