WebThe Probabilistic Satisfiability problem (PSAT) can be considered as a probabilistic counterpart of the classical SAT problem. In a PSAT instance, each clause in a CNF formula is assigned a probability of being true; the problem consists in checking the consistency of the assigned probabilities. Actually, PSAT turns out to be computationally much harder … WebThen you must show that, for every problem X in NP, X ≤ p SAT. The first part is by far the easiest. The satisfiablity problem can be expressed as a test for existence. φ is satisfiable …
