Hello, I am using different heuristics to get good solutions for a Routing Problem. I want to insert these solutions into the Branch and Bound tree and maintain the previously generated nodes, but when I insert a solution using the Start attribute, and run model.optimize(), the model is run from scratch, and I lose the previous Best Bound. Is there a way to do this?

Thank you!

  Hi Diego - 

  Please see our Knowledge Base article How do I inject a solution calculated in a separate process? for an example.
