Linear programming.
Apr 5, 2023 · In linear problems, as the name suggests, the objective (s) and constraints are described by linear functions only, which will be the focus of the current article. Throughout this article, some of the main theoretical aspects of linear programming will be covered, besides applications in classical problems using Python.
The goal of a linear programming problems is to find a way to get the most, or least, of some quantity -- often profit or expenses. This quantity is called your objective. The answer should depend on how much of some decision variables you choose. Your options for how much will be limited by constraints stated in the problem. De Anza College. Learning Objectives.
