The Linear Programming Problem is by far the most widely used optimization model. Its impact on economic and government modeling is immense. The Simplex Method for solving the Linear Programming (LP) Problem, due to George Dantzig, has been an extremely efficient computational tool for almost four decades. The method has been the subject of intense investigations for many years, but some major aspects of its behavior are not fully understood yet. The purpose of this paper is to survey the body of knowledge on the efficiency of the Simplex Method, from both practical and theoretical points of view. Adopting the number of iterations (pivot steps) as the yardstick for efficiency, we survey four aspects of the issue: 1. Reports on practical experience of the method's performance on real-life LP problems. 2. Results on controlled (Monte-Carlo) experiments solving LP problems which were randomly generated according to some predetermined distributions. 3. Complexity results, including theoretical analyses on both upper and lower bounds for the performance of the Simplex as well as non-Simplex algorithms for LP. 4. Results of recent theoretical studies using probabilistic analysis to derive bounds on the average behavior of the Simplex Method. We discuss the consequences and limitations of the various studies. Special emphasis is given to open questions.

In solving this problem, we will follow the algorithm listed above. STEP 1. Set up the problem. Write the objective function and the constraints. Since the simplex method is used for problems that consist of many variables, it is not practical to use the variables x, y, z etc. We use symbols x 1, x 2, x 3, and so on.

The Purpose of This Paper is to survey the body of knowledge on the efficiency of the Simplex Method and to point out major gaps which still exist in that knowledge. The number of iterations is used as the measure of efficiency throughout this paper, and other factors influencing efficiency are not addressed. Experimental and theoretical

Overview of the simplex method The simplex method is the most common way to solve large LP problems. Simplex is a mathematical term. In one dimension, a simplex is a line segment connecting two points. In two dimen-sions, a simplex is a triangle formed by joining the points. A three-dimensional simplex is a four-sided pyramid having four corners.

THE DUAL SIMPLEX METHOD. In Section 5, we have observed that solving an LP problem by the simplex method, we obtain a solution of its dual as a by-product. Vice versa, solving the dual we also solve the primal. This observation is useful for solving problems such as maximize 4x 1 8x 2 9x 3 subject to 2x 1 x 2 x 3 1 3x 1 4x 2 + x
