WebSchaefer's dichotomy theorem. In computational complexity theory, a branch of computer science, Schaefer's dichotomy theorem states necessary and sufficient conditions under which a finite set S of relations over the Boolean domain yields polynomial-time or NP-complete problems when the relations of S are used to constrain some of the ...

WebLadner's Theorem states that if P ≠ NP, then there is an infinite hierarchy of complexity classes strictly containing P and strictly contained in NP. The proof uses the … WebIn this lecture, we prove Ladner’s theorem using the technique of diagonalisation. Previously, we had de ned the complexity classes P and NP. The class P is a subset of NP. It is widely believed, but not been proved that P 6= NP. We have also de ned the class of NP …
