Exact Traveling Salesman Problem (TSP) solution in polynomial time?

发布于 2011-03-25 14:20:54

Is there an algorithm to solve the (time-indepenedent) TSP problem exactly (no heuristics, nodes are not points in space and costs are arbitrary) in polynomial time?

Thanks!

No. It is considered NP-Hard.

If you do find one, tell me (in secret of course) and we'll be rich together :-)

I know Wikipedia can be often wrong, but you might find their page on TSP interesting:
