Linear programming is a mathematical method used to find the best possible outcome in a given situation, such as maximizing profits or minimizing costs. It involves creating a model with linear relationships, where variables are represented by equations. The goal is to determine the optimal values of these variables while adhering to certain constraints, like resource limitations. In practical applications, linear programming can be used in various fields, including business, engineering, and logistics. For example, a company might use it to decide how much of each product to produce to maximize profits while considering factors like labor, materials, and production capacity.
