Dear support team,

I am developing a branch-and-cut algorithm for my problem. At the root node,  I want to use the callback function to define my own cut while turning the Gurobi internal cuts off. However, the internal cuts may be needed in other nodes. Is it possible to turn off these cuts only at the root node?

Thank you very much!

  Hi,

  Please have a look at our Knowledge Base article about changing parameters in a callback. This should resolve your issue.

  Best regards,
