Prove that travelling salesman is np complete

Webb14 juni 2024 · Vertex Cover (VC) Problem To prove VC is NP-complete we have to prove the following − VC is Non-deterministic Polynomial (NP). A NPC problem can be reduced into VC. To prove VC is NP, find a verifier which is a subset of vertices which is VC and that can be verified in polynomial time. For a graph of n vertices it can be proved in O (n2). WebbNow, a problem is NP-complete if it is both in NP, and NP-hard. Therefore you have two key, intuitive properties to NP-completeness. Easy to verify, but hard to find solutions. …

Webb19 mars 2014 · I have read that the classic travelling salesman problem (TSP) is NP-Hard. And there are some approximation algorithms and also a specific algorithm running in O (N^2 * 2^N) time. But AFAIK, these are for TSP in a general graph. So my question, is there a better (preferable polynomial time) algorithm for solving the TSP in a M x N grid? http://www.mathreference.com/lan-cx-np,sales.html
