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.

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. townhall organiseren

http://www.eecs.uwyo.edu/~ruben/static/pdf/tm2sat.pdf WebIn the early 1970s, Stephen Cook [31] and independently Leonid Levin [78] showed that the Boolean satisfiability problem (SAT)—whether a given a Boolean formula has a satisfying truth assignment—is NP-complete. Thus Boolean satisfiability is in P iff P = NP. This theorem has become known as the Cook–Levin theorem. Around the same time ...
