Hi Fan,

The MIPNODE callback is called once for each cut pass that occurs at the root node. This is described in more detail in the callback codes documentation.

I hope this helps. Thanks!

Hi Eli,

model.set(GRB_IntParam_Cuts, 0);

which means to shut off cuts.

Then why Gurobi still inserts cuts?

Best regards,

Fan

Hi Fan,

Gurobi is not inserting cuts if you turn off cuts. However, there are also other things going on in the root node, like for examples heuristics and this can also cause a log line to be printed.

Also can you share a log file?

Best regards,

Sonja

Hi Sonja,

Thanks for your reply. I got your point. I attached a picture.

OK, cool. This confirms that no cuts are generated and these are more or less heuristics that generate these lines.

Hi Sonja, thanks for your reply. I understand!
