We further probe an intermediate complexity for sparse and dense models by analysing circulant coupling matrices, that can be `rewired' to introduce greater complexity. A compelling approach for distinguishing easy and hard instances within the same NP-hard class of problems can be a starting point...
Our focus is on the complexity classes nondeterministic polynomial time (NP) and nondeterministic logarithmic space (NL). The presentation is aimed at computer science students at a senior undergraduate level, and assumes some familiarity with algorithm design and theory of computation. The material ...
P versus NP problem, in computational complexity (a subfield of theoretical computer science and mathematics), the question of whether all so-called NP problems are actually P problems. A P problem is one that can be solved in “polynomial time,” which
They rather conjectured that the problems in MMSNP exhibit a complexity dichotomy in the sense that they are either in P or NP-complete. The conjecture is based on their result that every problem in MMSNP is polynomial-time equivalent [7, 10] to a...
Complexity Class NP In computational complexity theory, NP ("Non-deterministic Polynomial time") is the set of decision problems solvable in polynomial time on a non-deterministic Turing machine. It is the set of problems that can be "verified" by a deterministic Turing machine in polynomial time...
[k⌈log n⌉— 1], the class of functions that are computable in polynomial k⌈log n⌉— 1 queries to an oracle in NP.¶We draw several observations and relationships between the following two properties of a complexity class C: whether there exists a truthtable hard p-selective ...

Closeness of NP-Hard Sets to Other Complexity Classes Let A be a language and C be a class of languages. A is said to be s-C-close (s-C-outside-close) if there exists $B \\in C$ such that $\\|(A\\Delta B)^{ \\... B Fu,HZ Li - 《Siam Journal on Computing》 被引量...
