  Hi,

  The C++ addVars function does not create a multidimensional array but a one dimensional array. In order to construct a 2 dimensional array of GRBVar objects, you can use

  GRBVar* v[47];
  for (int i = 0; i<47; i++)
  {
    v[i] = model.addVars(96);
  }

  You can then access the variables via \(\texttt{v[i][j]}\).

  Best regards,
  Jaromił
