NettetPCP: Undecidability Theorem (Undecidability of PCP) PCP isundecidable. Proof via an intermediate other problem modi ed PCP (MPCP) 1 Reduce MPCP to PCP (MPCP … NettetOne of the most important variants of PCP is the bounded Post correspondence problem, which asks if we can find a match using no more than k tiles, including repeated tiles. A brute force search solves the problem in time O(2 k ), but this may be difficult to improve upon, since the problem is NP-complete . [7]
