WebMay 11, 2024 · Using Cook-Levin on a NP-complete problem does not produce an exponential-sized output; it produces a polynomial-time circuit. It constructs a circuit whose size is polynomial in the number of steps taken by the NP-verifier; since the verifier runs in polynomial time, this circuit is polynomial in size. WebThe Cook-Levin Theorem states that 3SAT is \(\mathbf{NP}\) complete. Using a complex web of polynomial-time reductions, researchers have derived from the Cook-Levin theorem the \(\mathbf{NP}\)-completeness …

In computational complexity theory, the Cook–Levin theorem, also known as Cook's theorem, states that the Boolean satisfiability problem is NP-complete.
