Lecture 6: The Two-Phase Simplex Method September 9, 2019 University of Illinois at Urbana-Champaign 1 The problem we want to solve In the previous lecture, we took a shortcut. When our feasible region has the form fAx b;x 0g and b 0, the slack variables we add to put the program in equational form form our starting basis.

§ The utility is quite flexible with input. CHAPTER 17 Linear Programming: Simplex Method CONTENTS 17.1 AN ALGEBRAIC OVERVIEW 17.6 TABLEAU FORM: OF THE SIMPLEX METHOD THE GENERAL CASE Algebraic Properties of the Greater-Than-or-Equal-to Simplex Method Constraints Determining a Basic Solution Equality Constraints Basic Feasible Solution Eliminating Negative Right-Hand- Side Values 17.2 TABLEAU FORM Summary of the … SETTING UP THE FIRST SIMPLEX TABLEAU T3-3 As in the graphical approach, we begin the solution at the origin, where X 1 = 0,X 2 = 0, and profit = 0. The values of the two other variables,S 1 and S 2, then, must be nonzero. 3.1 Simplex Method for Problems in Feasible Canonical Form The Simplex method is a method that proceeds from one BFS or extreme point of the feasible region of an LP problem expressed in tableau form to another BFS, in such a way as to continually increase (or decrease) the value of the objective function until optimality is reached. The 3.3 Exercises – Simplex Method.

Convert the inequalities into equations. This is done by adding one slack variable for each inequality. Construct the initial simplex tableau. Write the objective function as the bottom row.

This gives us the equalities x+y +u = 4 2x+y = 5 We rewrite our objective function as −3x−4y+P = 0 and from here obtain the system of equations: x +y u = 4 2x+y = 5 −3x−4y +P = 0 This gives us our initial simplex tableau: Example: Simplex Method Iteration 1 (continued) • Step 3: Generate New Tableau Divide the second row by 1, the pivot element. Call the "new" (in this case, unchanged) row the "* row". Subtract 3 x (* row) from row 1. Subtract -1 x (* row) from row 3.
