WebIn 1978, Schaefer [12] considered a subclass of languages in NP and proved a “dichotomy theorem” for this class. The subclass considered were problems expressible as … WebAbstract. Schaefer proved in 1978 that the Boolean constraint satis-faction problem for a given constraint language is either in P or is NP-complete, and identified all tractable … Webvalues belongs to the underlying relation. Schaefer’s main result is a dichotomy theorem for the computational complexity of SAT(A), namely, depending on A, either SAT(A) is NP-complete or SAT(A) is solvable in polynomial time. Schaefer’s dichotomy theorem provided a unifying explanation for the NP-completeness of many well-known variants of phenyl-2-nitropropene reduction
