   Hey Guys,

My Funktion looks like this: sum of Y_i_j and sum of X_i_j

 

The Problem is, Y_i_j is a double and no iloNumVar.

It's part of the function anyway. As soon as i want to add the Term its not possible, because its a double and no IloNumVar

 

How can i solve this problem??

 

The code looks like this and the problem is written below

 

 

 

           IloLinearNumExpr Funktion = cplex.linearNumExpr();
              for (int i = 0; i < 2; i++) {
                  for (int j = 0; j < 3; j++) {
                      Funktion.addTerm(Y[i][j], 1.0);
                      Funktion.addTerm(X[i][j], 1.0);
                      
                      //Funktion.addTerm(cplex.sum(Y[i][j],X[i][j]));
                  }
              }

The method addTerm(double, IloNumVar) in the type IloLinearNumExpr is not applicable for the arguments (double, double)

 

 

The other question i have is, there is a constraint that expectes all Y-doubles to be bigger than 0

But the Term:  cplex.addGe(Y[0][0], 0.0);

 

is not available for double.

The method addGe(double, IloNumExpr) in the type IloCplexModeler is not applicable for the arguments (double, double)

 

Thanks for any help. Getting desperated.

 

Cheerfully regards Torben
