Hello again,<br><br>I have read in a number of places that the Tree Manager can "compute an initial upper bound using heuristics" based on a user-specified subroutine which can be run "before beginning to explore the branch and cut tree." <br>
<br>Are there any examples which do this? Which method should I override? Or is this meant to be run externally and then passed in somehow?<br><br>I can see (from the BAC example) how to override the generate_heuristic_solution() method, but this is called based on an LP solution at each node. I would like to generate a heuristic solution once before doing any branching (or solving the root node LP).<br>
<br>Thank you again for your time and patience, I really appreciate your help.<br><br>Jack<br><br><br>
