Why is travelling salesman problem np complete?

Webb14 sep. 2010 · As noted in the earlier answers, NP-hard means that any problem in NP can be reduced to it. This means that any complete problem for a class (e.g. PSPACE) which contains NP is also NP-hard.

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). 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? the new monsters in doorsWebb19 nov. 2013 · Here it is..
