This method, invented by George Dantzig in 1947, tests adjacent vertices of the feasible set (which is a polytope) in sequence so that at each new vertex the objective function improves or is unchanged. A simplex is the geometrical figure in n dimensions consisting of n+1 vertices. In 2-D it is a triangle, in 3-D a tetrahedron. The Simplex Algorithm for minimization takes such a set of n+1 points and attempts to move them into a minimum. The simplex formed from the points should be non-degenerate, it should have a non-zero volume. 2 Solving LPs: The Simplex Algorithm of George Dantzig 2.1 Simplex Pivoting: Dictionary Format We illustrate a general solution procedure, called the simplex algorithm,byimplementingit on a very simple example. Consider the LP (2.1) max5x 1 +4x 2 +3x 3 s.t.

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. This is the origin and the two non-basic variables are x 1 and x 2. To move around the feasible region, we need to move off of one of the lines x 1 = 0 or x 2 = 0 and onto one of the lines s 1 = 0, s 2 = 0, or s 3 = 0. Simplex 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. Maximization Problem in Standard Form We start with de ning the standard form of a linear programming The simplex method was developed during the Second World War by Dr. George Dantzig.
