WebbThe Simplex Method Complicated linear programs were difficult to solve until Dr. George Dantzig developed the simplex method. In this week, we first introduce the standard form and the basic solutions of a linear program. With the above ideas, we focus on the simplex method and study how it efficiently solves a linear program. WebbSimplex Method We will now consider LP (Linear Programming) problems that involve more than 2 decision variables. We will learn an algorithm called the simplex method which will allow us to solve these kind of problems.
