Homework: Code the Simplex Algorithm | Deadline: 23h59 19th October 2016 | The goal of this homework is for you to code the simplex algorithm and experiment with it. The choice of the programming language is up to you: C / C++ / Java / Python. If you want to use another language, please ask us beforehand. 1 Program Speci cations

Example: Let’s consider the following maximization problem. Initial construction steps : Build your matrix A. A will contain the coefficients of the constraints. Matrix b will contain the amount of resources. Derived by the concept of simplex and suggested by T. S. Motzkin, simplex method is a popular algorithm of mathematical optimization in the field of linear programming. 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.

Simplices are not actually used in the method, but one interpretation of it is that it operates on simplicial cones, and these become proper simplices with an additional constraint. The simplicial cones in question are the corners of a geometric object called a polytope. The shape of this po // Runs the simplex algorithm to optimise the LP. // Returns a vector of -1s if unbounded, -2s if infeasible. pair, double > simplex {if (initialise_simplex == - 1) {return make_pair (vector< double >(n + m, - 2), INFINITY);} int code; while (!(code = iterate_simplex ())); if (code == - 1) return make_pair (vector< double >(n + m, - 1), INFINITY); 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.

To become familiar with the execution of the Simplex algorithm, it is helpful to work several examples by hand. The Simplex Solver Implementation of the Simplex algorithm in Visual C++ Andy 20 October 2015 C++ / MFC / STL , Optimization No Comments An excellent implementation of the Simplex algorithm exists over at Google Code, written by Tommaso Urli: Write the initial tableau of Simplex method. The initial tableau of Simplex method consists of all the coefficients of the decision variables of the original problem and the slack, surplus and artificial variables added in second step (in columns, with P 0 as the constant term and P i as the coefficients of the rest of X i variables), and constraints (in rows).
