Webb5 dec. 2012 · Yes, of course you can use a branch-and-bound method. It will be slow for large input because TS is a hard problem, and your MIP formulation will have a lot of constraints (or a lot of variables): there is no "simple and fast" method. However, I was pointing out that simplex and branch-and-bound are different algorithms: the simplex is …
