Web6 de mai. de 1999 · Complexity of k-SAT. Abstract: The problem of k-SAT is to determine if the given k-CNF has a satisfying solution. It is a celebrated open question as to whether it requires exponential time to solve k-SAT for k/spl ges/3. Define s/sub k/ (for k/spl ges/3) to be the infimum of {/spl delta/: there exists an O (2/sup /spl delta/n/) algorithm for ... WebThe 1-in-3SAT problem was considered in Schaefer’s work on complexity of satis ability problems [9]. An inapproximability factor of 6=5 " was shown for 1-in-E3SAT in [6]. We are unaware of any comprehensive prior investigation into the complexity of approximating 1-in-kSAT and its variants for larger k.

On the other hand 1-Local Hamiltonian is in P, and hence not believed to be QMA-complete.
