The Simplex Algorithm Typical requirements for A level: Typically no more than three variables Formulation, including the use of slack variables Solution using simplex tableau Awareness of when the optimum is been reached Interpretation of results at any stage of the calculation

The simplex algorithm performs iterations into the extreme points set of feasible region, checking for each one if Optimalit criterion holds. Simplex Algorithm In General 1.Write LP with slack variables (slack vars = initial solution) 2.Choose a variable v in the objective with a positive coe cient to increase 3.Among the equations in which v has a negative coe cient q iv, choose the strictest one This is the one that minimizes p i=q iv because the equations are all of the form x i Before the simplex algorithm can be used to solve a linear program, the problem must be written in standard form. a. Constraints of type (Q) : for each constraint E of this type, we add a slack variable A Ü, such that A Ü is nonnegative. Example: 3 5 2 T 6 2 translates into 3 5 2 T 6 A 5 2, A 5 0 b. The Simplex Method We have seen that we are at the intersection of the lines x 1 = 0 and x 2 = 0.

The simplex algorithm is the classical method to solve the optimization problem of linear programming. We first reformulate the problem into the standard form in which all constraints are expressed as equalities.
