WebbComplicated 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. WebbRevised Simplex Method Steps. Step 1: Formalize the problem in standard form – I. Confirm that all b i ≥ 0. Maximization should be the objective function. Inequalities are converted to equations using non-negative slack variables. The first constraint equation is also treated as the objective function. Step 2: In the revised simplex form ...
