Cook–Levin theorem - Wikipedia

WebIn computational complexity theory, the Cook–Levin theorem, also known as Cook's theorem, states that the Boolean satisfiability problem is NP-complete.That is, it is in NP, … WebAdd a comment. 2. Since S A T is the first problem proven to be NP-complete, Cook proved that S A T is NP-complete using the basic definition of NP-completeness which says that to prove that a problem is NP-complete if all NP problems are reducible to it in polynomial time. So, Cook did this using the Turing Machine concept.
