Greetings,

I want to make a copy of a GRBModel, but I don't know how in c++. model.copy() works in python but not in c++.

I first have the followng class:

class MasterProblem

{

public:

GRBEnv* env = new GRBEnv();
GRBModel* modelo;

void set_init(GRBModel* in_modelo);

}

 

Then in the set_init function:

void MasterProblem::set_init(GRBModel* in_modelo){

if (in_modelo == NULL){

modelo = new GRBModel(*env);

}

else {

*modelo = in_modelo->copy();

}

}

 

However, it is said that GRBModel has no menber copy. Could anyone told me how to fix this?

Thanks!

  Hi Kechen,

  To copy a model in C++, you have to use the GRBModel constructor and pass the existing model as a parameter. This is explained here: GRBModel().

  I hope that helps!

  Cheers,
  Matthias
