The Content of Theorem • Simply: SAT is NP-complete problem • Actually, there is an explicit CNF formula f of length O(𝑓(𝑛)3 ) which is satisfiable if and only if N accepts w. In particular, when f(n) is a ...

WebProof of Cook-Levin Theorem: SAT is NP-complete • Already know SAT ∈ NP, 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 WebTheorem(Karp1972) 3COLisNP-complete.
