WebbIn this chapter, we will look at solving a specific Boolean satisfiability problem (3-Satisfiability) using Grover’s algorithm, with the aforementioned run time of O(1.414n) O ( 1.414 n). Interestingly, at the time of writing, the best-known classical algorithm for 3-Satisfiability has an upper-bound of O(1.307n) O ( 1.307 n) [3]. WebbAdd a comment. 3. CNF-SAT is in NP since you can verify a satisfying assignment in polynomial time. CNF-SAT is NP-hard since SAT is a special case of CNF-SAT, and so we can reduce the NP-hard problem SAT to the CNF-SAT. Since it is both in NP and NP-hard, we conclude that CNF-SAT is NP-complete.
