Web15.1 Proof of the Cook-Levin Theorem: SAT is NP-complete Already know SAT 2NP, so only need to show SAT is NP-hard. Let L be any language in NP. Let M be a NTM that decides L in time nk. We define a polynomial-time reduction f L: inputs 7!formulas such that for every w, M accepts input w iff f L(w) is satisfiable Reduction via “computation ...

WebThe Cook–Levin theorem is a theorem from theoretical computer science, which says that the Boolean satisfiability problem is NP-complete.A deterministic Turing machine can change a problem in NP in polynomial time to the problem of determining whether a Boolean formula is satisfiable. An important consequence of the theorem is that if there exists a … WebThe Cook-Levin Theorem Recall that a language Lis NP-complete if L2NP and if Lis at least as hard as every language in NP: for all A2NP, we have that A P L. Our rst NP-complete language is the hardest to get, since we have no NP-hard language to reduce to it. A rst NP-complete language is provided by the Cook-Levin
