ABSTRACT
Linear programming is a powerful tool used extensively in many agricultural, feed, and food operations. A classic type of problem it solves is to select the amount of ingredients to put in a mixture to meet certain criteria, or constraints, such as “Protein content must be at least 15%,” and “Select the lowest-cost combination of these ingredients.” Often there is an almost infinite number of combinations of types and amounts of ingredients that will meet the criteria, but the manufacturer obviously wants to minimize the cost of the mixture.
