Hi,

I need to learn about how can I write in Gurobi the Barrier Display option. What I mean that in cplex Barrier Display parameter can be selected among 0, 1 and 2 which sets the level of barrier progress information to be displayed. Is there anything in Gurobi to display Barrier progress information.

model.set(GRB.);
//model.setParam(IloCplex.Param.Barrier.Display, 2); //cplex

 

Furthermore, I need to select barrier starting point algorithm. However, in gurobi I could not find such a parameter.

model.set(GRB.IntParam.      , Parameters.BARRIER_ALGORITHM); //barrier starting point algorithm
//model.setParam(IloCplex.Param.Barrier.StartAlg, Parameters.BARRIER_ALGORITHM); // cplex version

 

Thank you so much.

Best Regards

  Hi,

  Please excuse the late answer.
  
  We do not have a setting to control the output level of the Barrier algorithm. Do you need a specific information which is missing in the current output?

  We currently don't have a parameter to control the algorithm for starting point estimation. Do you have specific experience with the corresponding CPLEX parameter? Do you think that Gurobi's Barrier starting point algorithm is missing something?

  Best regards,
  Jaromił
