How to Apply a Globally Valid Set of Cuts After Root Cut Generation #598
-
|
I have a set of cuts that I know are valid for a MILP. I would like to add them to the pool of cuts that are considered for every node in the branch and bound tree, and I would like to do so after cut generation at the root node has completed. How can I do so? |

You want to create a cut generator from CglStored and add that to the model. Look at Cbc/examples/allCuts.cpp. This may be out of date but will get you started. You may be better off using a more flexible example e.g. driver6.cpp and using a call back to add the generator. |

I'll have a look and write back my solution for anyone curious in the future. Thank you for the pointer! |
