WebThe Cook–Levin theorem states that the Boolean satisfiability problem is NP-complete, thus establishing that such problems do exist. In 1972, Richard Karp proved that several other problems were also NP-complete (see Karp's 21 NP-complete problems ); thus, there is a class of NP-complete problems (besides the Boolean satisfiability problem). WebMar 6, 2024 · In computational complexity theory, the Cook–Levin theorem, also known as Cook's theorem, states that the Boolean satisfiability problem is NP-complete. That is, it is in NP, and any problem in NP can be reduced in polynomial time by a deterministic Turing machine to the Boolean satisfiability problem. The theorem is named after Stephen … brown recluse vs garden spider

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.
