I have this optimization probem to solve. Its a mix integer programming problem. However, I don’t know how to use two or more variables in the objective function. I have used this code
sum_of_Pgu_over_g = sum(P_gu,1);
sum_of_departuregu_over_u = sum(departure_gu,2);
variables P_gu Z sum_of_Pgu_over_g sum_of_departuregu_over_u;
dual variable lambda1 lambda2 lambda3 lambda4 lambda5 lambda6;
minimize P_gu Z sum_of_Pgu_over_g sum_of_departuregu_over_u
It gives me the error in the objective function line “Error: Unexpected MATLAB expression.”, due to which I cannot proceed.
