Q7-Consider the following form of the Lagrangian: 2 2 L= w;W; Oij +1 (wifi 1 (3 43-4) +- (-1) i=1 j=1 1. In order to implement the above model, indicate clearly how many variables you must esti- mate? (5 pts.) 2. Write down the decision variables. (5 pts.) 3. Set up the F.O.N.C by explicitly writing each step. Make all the required simplifications. (10 pts.) 4. How many equations do you need to solve in order to find the optimum solution? (5 pts.)
