3 Optimization [15pts + 4pts Bonus for All] Optimization problems are related to minimizing a function (usually termed loss, cost or error function) or maximizing a function (such as the likelihood) with respect to some variable x. The Karush-Kuhn- Tucker (KKT) conditions are first-order conditions for a solution in nonlinear programming to be optimal, provided that some regularity conditions are satisfied. In this question, you will be solving the following optimization problem: $\max_{x,y} \quad f(x,y) = -4y + xy$ $\text{s.t.} \quad g_1(x,y) = 2x^2 + y^2 \le 12$ $\quad g_2(x,y) = x \le 1$ (a) Write the Lagrange function for the maximization problem. Now change the maximum function to a minimum function (i.e. $\min_{x,y} f(x,y) = -4y + xy$) and provide the Lagrange function for the minimization problem with the same constraints $g_1$ and $g_2$. [2pts] Note: The minimization problem is only for part (a). (b) List the names of all of the KKT conditions and its corresponding mathematical equations or inequalities for this specific maximization problem [2pts] (c) Solve for 4 possibilities formed by each constraint being active or inactive. Do not forget to check the inactive constraints for each point. Candidate points must satisfy the inactive constraints. [5pts] (d) List the candidate point(s) (there may be 0, 1, 2, or any number of candidate points) [4pts] (e) Find the one candidate point for which f(x,y) is largest. Check if L(x,y) is concave or convex at this point by using the Hessian in the second partial derivative test. [2pts] HINT 1: Click here for an example maximization problem.

PROBLEM SET A Problem 20-1A Manufacturing: Preparing production and manufacturing budgets C2 P1 connect Black Diamond Company produces snow skis. Each ski requires 2 pounds of carbon fiber. The company's management predicts that 5,000 skis and 6,000 pounds of carbon fiber will be in inventory on June 30 of the current year and that 150,000 skis will be sold during the next (third) quarter. A set of two skis sells for $300. Management wants to end the third quarter with 3,500 skis and 4,000 pounds of carbon fiber in inventory. Carbon fiber can be purchased for $15 per pound. Each ski requires 0.5 hours of direct labor at $20 per hour. Variable overhead is applied at the rate of $8 per direct labor hour. The company budgets fixed overhead of $1,782,000 for the quarter. Required 1. Prepare the third-quarter production budget for skis. 2. Prepare the third-quarter direct materials (carbon fiber) budget; include the dollar cost of purchases. 3. Prepare the direct labor budget for the third quarter. 4. Prepare the factory overhead budget for the third quarter. Check (1) Units manuf., 148,500; (2) Cost of carbon fiber purchases, $4,425,000
