I am trying to set a MIP start with Gurobi MILP solver. I have a set of binary variables : tupledict_m = master.addVars(list_m, name="m", vtype=GRB.BINARY) where master is a Gurobi Model, list_m is an tuple of integers. I run the following to set the starting values : for i in list_m: tupledict_m.start = bool(m_values) where m_values is either 1.0 or 0.0 with float data type. Right after that if I print rint([tupledict_m.start for i in list_m]) I get 1e+101 everywhere. Any idea on why and how to fix that ? Continue reading...
