SpletFormal statement. The PCP theorem states that NP = PCP[O(log n), O(1)],. where PCP[r(n), q(n)] is the class of problems for which a probabilistically checkable proof of a solution can be given, such that the proof can be checked in polynomial time using r(n) bits of randomness and by reading q(n) bits of the proof, correct proofs are always accepted, … Splet18. nov. 2024 · The PCP theorem says that any mathematical proof can be written in a special "PCP" format such that it can be verified, with arbitrarily high probability, by sampling only a few symbols in the proof. Hence the name, … Splet1.1 Toward Understanding the Power of PCP An easy observation is that PCP(0;poly) = NP. In fact, we have the following stronger result: Lemma 1 PCP(log;poly) = NP.
