Linear Optimization often goes by the name Linear Programming (LP). The word "Programming" should not be confused with computer programming which in fact it antedates. As originally used, the term refers to the timing and magnitude of actions to be carried out so as to achieve a goal in the best possible way. Learn the basics of linear programming, a powerful tool for solving optimization problems over Rn. See how to identify decision variables, write objective and constraint functions, and solve a simple example of maximizing profit at a plastic cup factory.
