class np造句

例句与造句

1. Moreover, the class NP class.
2. It is not known whether the Euclidean Steiner tree problem is NP-complete, since membership to the complexity class NP is not known.
3. Awkwardly, it does not restrict the class NP-hard to decision problems, for instance it also includes search problems, or optimization problems.
4. Since deterministic Turing machines are special non-deterministic Turing machines, it is easily observed that each problem in P is also member of the class NP.
5. The problem is not known to be solvable in polynomial time nor to be NP-complete, and therefore may be in the computational complexity class NP-intermediate.
6. It's difficult to find class np in a sentence. 用class np造句挺难的
7. Adleman brought DNA computers to the world's attention in 1994 by solving a simple version of the traveling salesman problem, which also belongs to the class NP-complete.
8. The sign problem is NP-hard, implying that a full and generic solution of the sign problem would also solve all problems in the complexity class NP in polynomial time.
9. It is known that the graph isomorphism problem is in the low hierarchy of class NP, which implies that it is not NP-complete unless the polynomial time hierarchy collapses to its second level.
10. The complexity class NP, on the other hand, contains many problems that people would like to solve efficiently, but for which no efficient algorithm is known, such as the Boolean satisfiability problem, the Hamiltonian path problem and the vertex cover problem.
11. A propositional proof system is a certificate-verifier for membership in TAUT . Existence of a polynomially bounded propositional proof system means that there is a verifier with polynomial-size certificates, i . e ., TAUT is in NP . In fact these two statements are equivalent, i . e ., there is a polynomially bounded propositional proof system if and only if the complexity classes NP and coNP are equal.
12. This means that all problems in the complexity class NP, which includes a wide range of natural decision and optimization problems, are at most as difficult to solve as SAT . There is no known algorithm that efficiently solves each SAT problem, and it is generally believed that no such algorithm exists; yet this belief has not been proven mathematically, and resolving the question whether SAT has a polynomial-time algorithm is equivalent to the P versus NP problem, which is a famous open problem in the theory of computing.
