WebNov 24, 2024 · The functionality of the above NOT gate in CNF form is: From the above gates, we can observe that we can convert the circuit into an equivalent CNF form. Hence all NP-Hard problems can be reduced to CNF, which means, they can be reduced to an SAT problem. Hence the SAT is NP-Complete. 6. Introduction to 3-SAT WebSAT NPC. Proof. SAT NP since certificate is satisfying assignment of variables. To show SAT is NP-hard, must show every L NP is p-time reducible to it. Idea: Use p-time verifier A(x,y) of L to construct input of SAT s.t. verifier says yes iff satisfiable WebYou can go from any formula to a CNF which is satisfiable exactly when the original formula is in polynomial time. This is why CNF-SAT is NP-complete. Any SAT instance (an NP-complete problem) can be reduced to CNF-SAT in polynomial time. lauren heady
