NP-Completeness of (k-SAT,r-UNk-SAT) and (LSAT≥k,,r-UNLSAT≥k) k-CNF is the class of CNF formulas in which the length of each clause of every formula is k. The decision problem asks for an assignment of truth values to... Tianyan Deng,Daoyun Xu - Annual International Worksho...
Reductions, completeness and the hardness of approximability G. Ausiello, V.Th. Paschos, in European Journal of Operational Research, 2006 In this paper we illustrate the important role played by reductions as regards the approximate solution of hard combinatorial optimization problems.1 As it is ...
As a corollary, using the fact that a secret-sharing scheme for a language implies witness encryption for that language and using the completeness of witness encryption,Footnote9we obtain a completeness theorem for secret-sharing. Corollary 1.2 ...
In other words, it fails to grapple with the central insight of NP-completeness: that for the purposes of P =? NP, all these problems are just re-encodings of one another. It's sometimes claimed that, when we consider P =? NP, there's a "symmetry of ignorance": yes, we have no...
Full size image In the honest case, the test passes with certainty and therefore it has perfect completeness, while it was shown in Ref. 27 that the test also has constant soundness. Overall, by selecting randomly between these three tests, Arthur can verify Merlin’s proof with perfect compl...
Therefore, the NP-completeness of the weighted independent domination problem in chordal graphs follows from that of the domination problem in general graph. For any graph G=(V,E), consider the chordal graph G′=(V′,E′) with vertex setV′={v1,v2,v3,v4|v∈V}and edge setE′={v1v2...
