WebJul 7, 2024 · – Hence the halting problem is an NP-hard problem which is not in NP. Why can a Turing machine not solve the halting problem? Turing proved no algorithm exists that always correctly decides whether, for a given arbitrary program and input, the program halts when run with that input. The essence of Turing’s proof is that any such algorithm ... WebJun 5, 2024 · Reducibility: Undecidable Problems that is recursively enumerable, A Simple Un-decidable problem.

How to Prove That a Math Problem Is Np-Hard or Np-Complete
WebAug 14, 2024 · Such yes/no problems for which, if the answer is yes, we can efficiently demonstrate that, belong to NP. Any solution to a problem serves to convince us of the answer, and so P is contained in NP. Web4 Answers.

Then A is clearly reducible to B and B is N P -hard (any computable problem can be reduced to halting problem in polynomial time), but A isn't N P -complete (as it's not in N P ). For 2), let A be any N P -complete problem (for example, 3-SAT) and let B be halting problem. lapapaisti
