Chapter 4: Problem 45

Give one possible advantage of using duality to solve a standard minimization problem.

Short Answer

Expert verified
One possible advantage of using duality to solve a standard minimization problem is that it can reduce the complexity of the primal problem, leading to faster and more efficient computations. The dual problem may have a more manageable structure or fewer variables and constraints than the original problem. Moreover, duality provides a deeper insight into the problem by connecting properties of the optimal solutions of the primal and dual problems, which can aid in deriving important insights or bounds for the primal problem's solution.

Step by step solution

01

Introduction to Duality in Optimization

Duality is a concept in optimization theory, specifically in linear and convex programming. It provides a relationship between a given optimization problem, known as the primal problem, and another optimization problem, known as the dual problem. The dual problem can be thought of as a different perspective on the original problem, and often involves switching the roles of the objective function and constraints. This helps in simplifying and finding a more efficient solution to the original problem.

Advantage of using Duality

One possible advantage of using duality to solve a standard minimization problem is to reduce the complexity of the primal problem. In some cases, the dual problem may have a more manageable structure or fewer variables and constraints than the original problem. This can lead to faster and more efficient computations. Furthermore, duality provides a deeper insight into the problem, since properties of the optimal solutions of the primal and dual problems are connected. By solving the dual problem, it may be easier to derive important insights or bounds for the primal problem's solution.

You manage an ice cream factory that makes two flavors: Creamy Vanilla and Continental Mocha. Into each quart of Creamy Vanilla go 2 eggs and 3 cups of cream. Into each quart of Continental Mocha go 1 egg and 3 cups of cream. You have in stock 500 eggs and 900 cups of cream. You make a profit of \(\$ 3\) on each quart of Creamy Vanilla and \(\$ 2\) on each quart of Continental Mocha. How many quarts of each flavor should you make in order to earn the largest profit?

Politics The political pollster Canter is preparing for a national election. It would like to poll at least 1,500 Democrats and 1,500 Republicans. Each mailing to the East Coast gets responses from 100 Democrats and 50 Republicans. Each mailing to the Midwest gets responses from 100 Democrats and 100 Republicans. And each mailing to the West Coast gets responses from 50 Democrats and 100 Republicans. Mailings to the East Coast cost \(\$ 40\) each to produce and mail, mailings to the Midwest cost \(\$ 60\) each, and mailings to the West Coast cost \(\$ 50\) each. How many mailings should Canter send to each area of the country to get the responses it needs at the least possible cost? What will it cost?

Each serving of Gerber Mixed Cereal for Baby contains 60 calories and no vitamin \(C\). Each serving of Gerber Mango Tropical Fruit Dessert contains 80 calories and 45 percent of the U.S. Recommended Daily Allowance (RDA) of vitamin \(\mathrm{C}\) for infants. Each serving of Gerber Apple Banana Juice contains 60 calories and 120 percent of the U.S. RDA of vitamin \(\mathrm{C}\) for infants. \(^{42}\) The cereal costs \(10 \mathrm{~d} /\) serving, the dessert costs \(53 \mathrm{~d} /\) serving, and the juice costs 27 d/serving. If you want to provide your child with at least 120 calories and at least 120 percent of the U.S. RDA of vitamin \(\mathrm{C}\), how can you do so at the least cost? What are your shadow costs for calories and vitamin \(\mathrm{C}\) ?
