3 Numerical Methods for Unconstrained Problems There are several numerical methods that are available for solving unconstrained optimization problems. Some of the methods are Steepest descent, Conjugate gradient, and Newton's method. Different methods have their strengths and weaknesses. Chapter 5 presents several methods for unconstrained problems. 4 The Simplex Method This is an efficient and robust algorithm for solving linear programming problems. The method can easily handle problems with thousands of variables and constraints.

A salesman is trying to sell a \$55,000 piece of equipment to the Turner Construction Co. of Iowa City. Using this equipment, the company can generate net annual revenue before taxes of \$15,000 over the next five years. The equipment has a salvage value of \$5,000 at the end of five years. The tax laws allow straight-line depreciation of equipment, which means that the company can deduct \$10,000 horn its yearly taxable income. The income tax rate for the company is 34%. The company likes to make at least 8% annually on their investments after all taxes are paid.

Time for loading and unloading the mixer is negligible. Using present worth analysis, formulate the problem of determining the capacity of the mixer and the stirrer power in order to minimize cost. Assume a 5-year useful life, 9% annual interest rate compounded monthly, and a salvage value of 10% of the initial cost of the mixer. 27. 26. 28. A multicell evaporator is to be installed to evaporate water from a salt water solution in order to increase the salt concentration in the solution. The initial concentration of the solution is 5% salt by weight.
