On the complexity of k-sat
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 … Web1 de mar. de 2024 · Let (k, s)-SAT be the k-SAT problem restricted to formulas in which each variable occurs in at most s clauses. It is well known that (3, 3)-SAT is trivial and (3, 4)-SAT is NP-complete.Answering a question posed by Iwama and Takaki (DMTCS 1997), Berman, Karpinski and Scott (DAM 2007) gave, for every fixed t ≥ 0, a polynomial-time …

WebWe give hundreds of new exact Rado number values and describe a SAT-based method to produce formulas for three infinite families of three-color Rado numbers. If time permits, we will also discuss the connections between Ramsey theory and complexity of Nullstellensatz certification. We show that a broad class of “Ramsey-type” problems have ... 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} \}.
