Cook's theorem in detail
WebA problem is NP-hard if all problems in NP are polynomial time reducible to it, even though it may not be in NP itself. If a polynomial time algorithm exists for any of these problems, all problems in NP would be polynomial time solvable. These problems are called NP-complete. The phenomenon of NP-completeness is important for both theoretical ... WebMar 12, 2024 · 0. Based on Cook's theorem, Any NP problem can be converted to SAT in polynomial time. I know that SAT is a NP-complete problem. Therefore, is it accurate to say: If we can reduce a search problem A (which is in NP) to problem B in a polynomial number of steps, then problem B must be NP-complete? time. np. p-np. Share.
