I wanted to test different model formulations for their performance. In order to do so, I turned off heuristics (C++ API) by setting model.set(GRB_DoubleParam_Heuristics, 0.00);
However, quite often the log still reports that a heuristic solution has been found. As far as I could see this mostly happens before branching starts but sometimes also within the tree.
Does anyone know if this behavior desired?
If so, is there a way to completely turn off heuristics?
