A Mechanical Proof of the Cook-Levin Theorem

WebThis process is possible since Cook and Levin used the logical structure of NP to prove that SAT, and as a corollary 3-SAT, are NP-complete. This makes SAT the "first" NP-complete problem and we reduce other canonical NP-complete problems (e.g. … WebTheorem-4.

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.
