This list will be very long;) Here are some of my favourite (NP-complete) variants of SAT: PLANAR ( ≤ 3, 3 )-SAT (each clause contains at least two and at most three literals, each variable appears in exactly three clauses; twice in its non-negated form, and once in its negated form, and the bipartite incidence graph is planar.)

Web(1)The worst case time complexity of k-SAT with n variables and m clauses reaches the maximum value, if m is Cn where C is a constant. (2)The exponential time hypothesis. This question comes from a view about input size of problems. For example, an instance of 3-SAT with n variables is a 3CNF formula and the length of the formula could be O(n^3). WebThe k-LOCAL HAMILTONIAN problem is a natural complete problem for the complexity class QMA, the quantum analog of NP. It is similar in spirit to MAX-k-SAT, which is NP-complete for k ≥ 2. It was known that the problem is QMA-complete for any k ≥ 3. On the other hand 1-LOCAL HAMILTONIAN is in P, and hence not believed to be QMA-complete.

WebSAT was the first known NP-complete problem, as proved by Stephen Cook at the University of Toronto in 1971 and independently by Leonid Levin at the Russian Academy of Sciences in 1973. Until that time, the concept of an NP-complete problem did not even exist. The proof shows how every decision problem in the complexity class NP can be …
