Proof that tsp is np hard
WebMar 19, 2014 · Proving TSP in NP-Hard (from the method I know), is done using the fact that Hamiltonian-Path is NP-Hard. On grids graphs, Hamiltonian-Path is in P, hence the same method to prove it is NP-Hard won't work. I provide here as well an example why the degree of each node is not necessarily a good indication if the problem is hard. Webin NP. De nition 22.2 (NP-hard) A problem is NP-hard if all problems in NP can be reduced to it in poly-time. We can see that NP-hard problems are "harder" than all problems in NP. By reduction, or more speci cally reducing problem B to problem A, we mean that given a \blackbox" solver that solves A, we can also solve

If the optimal solution to the TSP can be found in polynomial time, it would then follow that every NP-hard problem could be solved in polynomial time, proving P=NP.
