In computational complexity theory, polynomial creativity is a theory analogous to the theory of creative sets in recursion theory and mathematical logic. The k-creative sets are a family of formal languages in the complexity class NP whose complements certifiably do not have -time nondeterministic recognition algorithms.

Property Value
dbo:abstract
  • In computational complexity theory, polynomial creativity is a theory analogous to the theory of creative sets in recursion theory and mathematical logic. The k-creative sets are a family of formal languages in the complexity class NP whose complements certifiably do not have -time nondeterministic recognition algorithms. The k-creative sets are conjectured to form counterexamples to the Berman–Hartmanis conjecture on isomorphism of NP-complete sets. It is NP-complete to test whether an input string belongs to any one of these languages, but no polynomial time isomorphisms between all such languages and other NP-complete languages are known. Polynomial creativity and the k-creative sets were introduced in 1985 by Deborah Joseph and Paul Young, following earlier attempts to define polynomial analogues for creative sets by Ko and Moore.
