TSP Subtour-Elimination Callback Class
I am new to Xpress and trying to implement a simple TSP instance using BCL Java to get myself up to speed. I have done this in Cplex before using the cut callbacks, which work fine for adding the sub...
Thanks a bunch for your response. In the example f5tour.mos, my understanding is that it re-solves the whole problem from scratch after adding each subtour cut. If so, is there a way to implement do this in Mosel via a callback method that adds subtour cuts as necessary within the B&B tree?
As for BCL, I made the changes that you suggested but it still does not like the cut I am adding. Any idea what else might be going wrong here?
Code attached.
