Part (b). We need to show, for every problem X in …
WebbSAT is in NP There is a multitape NTM that can decide if a Boolean formula of length n is satisfiable. The NTM takes O(n2) time along any path. Use nondeterminism to guess a … WebbSAT (Boolean satisfiability problem) is the problem of assigning Boolean values to variables to satisfy a given Boolean formula. The Boolean formula will usually be given in CNF (conjunctive normal form), which is …
Webb7 dec. 2015 · In order to show that some problem is NP-hard, we to show that it is at least as hard as SAT, that is, given an arbitrary instance of SAT, convert it to an instance of … WebbConsider resolution on a 2-SAT formula. Any resolvent is of size at most 2 (note that n + m − 2 ≤ 2 if n, m ≤ 2 for clauses of length n and m resp). The number of clauses of size 2 is quadratic in the number of variables. Therefore, the resolution algorithm is in P.
WebbYour set is in P, as established earlier. If P = N P then every nontrivial set S that's in P is actually N P -complete (nontrivial means: there is at least one string x ∈ S and one string y ∉ S ). If P = N P we have a polytime SAT algorithm.
