I have implemented this concept assuming that a is a normal array type variable with the following expression.   int *a = new int [n_robo]; GRBVar w3 = model.addVar(0, 100, 1, GRB_CONTINUOUS); GRBV...

Dear Marika, Thank you for your prompt reply! In the above code, w3 is a normal integer type variable in C++. Now, my intention is to store an integer value (say x) w3 from the set of integer value...

Thanks, Riley. I debug the model and identified the issue. The representation of the precedence constraint was incorrect in the model and therefore, it shows infeasible results. 

Dear Riely,Thank you very much for your comment. I have changed the model and its running. However, I face another issue. It shows that the model has got an optimal result, but the actual optimal r...
