One of the greatest achievements of Theoretical Computer Science was to show NP-hardness of *approximation* problems. This required a new, surprising understanding about the power of NP: All NP problems have proofs that can be checked probabilistically by reading only a *constant* number of proof symbols. This Theorem became known as the PCP Theorem (PCP stands for Probabilistically Checkable Proofs). |
