Web4 de mai. de 1999 · 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 \geq 3.Define s_k (for k\geq 3) to be the infimum of \{\delta: \mbox{there exists an O(2^{\delta n})} \mbox{ algorithm for solving k-SAT} \}. Web1 de mar. de 2024 · For k ≥ 3, the k-SAT problem is the restriction of SAT to k-CNF formulas. It is well known and readily seen that 2-SAT is polynomial-time solvable, whereas 3-SAT is NP-complete [10]. This led to numerous studies on further restrictions and variants of SAT. We focus on the (k, s)-SAT problem, which is the restriction of k-SAT to (k, s) …
