Part 1: Optimization with inequality constraints 1. A consumer lives on an island. Her utility function is U = (x²y)1/3. She produces two goods, x and y. She faces a production constraint and an environmental constraint: Her production possibility frontier is: x² + y2 s 300. She faces an environmental constraint given by x + y = 200. a) Set up the Lagrangian function. b) List all of the Kuhn-Tucker conditions. c) Interpret...

a) Formulate a cost function along with constraints, if any, for the following optimization problems. You don't need to solve any of these problems. i) Two electric generators are interconnected to provide total power to meet the load. Suppose each generator's cost (C) is a function of its power output P (in terms of units), and costs per unit are given by: C2 = 1 + 0.6P2 + P22 (for Generator 2). -1-P -Pi2 (for Generator 1), If the total...

4. (4 pt) Answer True or False a. A positive definite quadratic form must have positive value for any b. The Hessian of an unconstrained function at its local minimum point must be positive semidefinite. С. If a slack variable has zero value at the optimum point, the inequality constraint is inactive. d. At the optimum point, the number of active independent constraints is always more than the number of design variables. e. At the optimum...

Formulate the followings into
optimization problems. While you could use the integer constraints,
the linear structure should be maintained. However, you shouldn’t
use the integer constraints if you can formulate the problem
without them. Describe the decision variables, objective function
and constraints carefully. You don’t need to solve this
problem.
