I have been trying to use the SetHint python API in google or-tools to warm start MIPs and solve it using CPLEX. It looks like my hints are accepted by the SetHint function but I am not sure whether CPLEX is actually using the warm start, the CPLEX output log has nothing related to warm start.
I have set the following parameters in CPLEX through or-tools
solver.SetSolverSpecificParametersAsString(f"CPLEX Parameter File Version 188.8.131.52 \n CPXPARAM_Advance 1 \n CPXPARAM_MIP_Display 3 \n CPXPARAM_MIP_Limits_RepairTries 100 ")
Does the SetHint API work with CPLEX? Is there a way to warm start CPLEX using or-tools?
