Web31 de mai. de 2024 · A complete k -CNF formula on n variables ( k ≤ n) is a k -CNF formula which contains all clauses of width k or lower it implies. Let us define the (Complete/Assign) 3-SAT problem: Given F, a complete 3-CNF formula on n variables and I, a partial assignment of l literals among n (where l ≤ n ). Let F I be the induced formula obtained by ...

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) … 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. ctm scottburgh https://maskitas.net

WebThe k-SAT problem is to determine if a given k-CNF has a satisfying assignment. It is a celebrated open question as to whether it requires exponential time to solve k-SAT for k 3. Here exponential time means 2 n for some >0. In this paper, assuming that,... Web17. 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.)
