For More Information 3.9.9 Linear Programming FindMinimum can find local minima for arbitrary functions. In solving optimization problems, it is however often important to be able to find global maxima and minima. Linear programming provides a way to do this for linear functions. In general, linear programming allows you to find the global minimum or maximum of any linear function subject to a set of constraints defined by linear inequalities. For a function of variables, the constraints effectively define a region in -dimensional space. Each linear inequality gives a plane in -dimensional space which forms one of the sides of the region. Solving linear optimization problems. The functions ConstrainedMax and ConstrainedMin allow you to specify an "objective function" to maximize or minimize, together with a set of linear constraints on variables. Mathematica assumes in all cases that the variables are constrained to have non-negative values.

Home Gizmos Math Linear Programming Introduction Why use Gizmos? With this Gizmo, you will experiment with finding the maximum (or minimum) value of a linear equation in two variables subject to linear constraint inequalities. Are there any general rules governing where the maximum or minimum can occur? Lets find out. Linear Programming Exploration Guide In the upper left corner of the Gizmo is a function in x and y. This is the function that you are going to extremize in order to find the places where the function value is at its maximum and minimum. When we need to extremize a function, there are usually practical constraints on x and y that limit which (x,y) coordinates we can choose from. For instance, if x represents the time to spend on a particular task, you might have a constraint of 'x cannot be negative', or if y represents the cost of producing a product, you might have a constraint of 'y cannot exceed 10.00.' More complicated constraints relate x and y to one another, such as 'x + y is less than 16.' Taken together, these constraints describe a

As the name implies, the functions must be linear in order for linear programming techniques to be used. Problem Formulation Checklist The objective function and constraints are formulated from information extracted from the problem statement. The following checklist is useful for minimizing the risk of errors in problem formulation. Every number in problem statement should be either implemented in the formulation or rejected as irrelevant, e.g. sunk costs. Don't forget any initial conditions, e.g. initial staff on hand at beginning of first staffing period. Ensure every variable in the objective function is listed somewhere in the constraints. Ensure that any non-negativity constraints are listed.

Linear Programming is a technique used to solve problems that have many numeric constraints. Often these constraints have poorly defined relationships, and nobody knows how to find the best solution. In these cases, the best outcome is to find a good solution. Often the goal is to either minimise a cost or maximise a value. The relationships have to be defined mathematically, usually by inequalities. Sometimes more than one goal may be defined. In these cases, the goals are usually either prioritized, or weighted. Because techniques are limited, the constraints are usually described as linear inequalities. Mathematicians can handle lines. Graphically, a linear inequality is a line that relates two types of numbers on a graph. Every point on one side of the line is an impossible solution; it simply will not work. Every point on the other side represents a possible solution, but most of these will be wasteful. The points on the line are usually good solutions because they give the maximum result from a minimum of resource.

SIAM Journal on Computing Volume 29, Number 6 pp. 2074-2097 Gadgets, Approximation, and Linear Programming Luca Trevisan, Gregory B. Sorkin, Madhu Sudan, David P. Williamson Abstract. We present a linear programming-based method for finding "gadgets," i.e., combinatorial structures reducing constraints of one optimization problem to constraints of another. A key step in this method is a simple observation which limits the search space to a finite one. Using this new method we present a number of new, computer-constructed gadgets for several different reductions. This method also answers a question posed by Bellare, Goldreich, and Sudan [ SIAM J. Comput., 27 (1998), pp. 804915] of how to prove the optimality of gadgets: linear programming duality gives such proofs. The new gadgets, when combined with recent results of Hå stad [ Proceedings of the th ACM Symposium on Theory of Computing SIAM J. Comput. J. ACM , 42 (1995), pp. 11151145]; U. Feige and M. X.

Vanderbei Dept. of Civil Engineering and Operations Research, Princeton University, NJ, USA Book Series: INTERNATIONAL SERIES IN OPERATIONS RESEARCH AND MANAGEMENT SCIENCE Volume 4 This book focuses largely on constrained optimization. It begins with a substantial treatment of linear programming and proceeds to convex analysis, network flows, integer programming, quadratic programming, and convex optimization. Along the way, dynamic programming and the linear complementarity problem are touched on as well. This book aims to be the first introduction to the topic. Specific examples and concrete algorithms precede more abstract topics. Nevertheless, topics covered are developed in some depth, a large number of numerical examples worked out in detail, and many recent results are included, most notably interior-point methods. The exercises at the end of each chapter both illustrate the theory, and, in some cases, extend it. Optimization is not merely an intellectual exercise: its purpose is to solve practical problems on a computer. Accordingly, the book comes with software that implements the major algorithms studied. At this point, software for the following four algorithms is available:

Introduction to GLPK GLPK ( G NU L inear P rogramming K it) is a set of routines written in ANSI C and organized in the form of a library. This package is intended for solving large-scale linear programming (LP), mixed integer linear programming (MIP), and other related problems. GLPK has the following main features: implementation of the revised simplex method (based on sparse matrix technique, steepest edge pricing, and two-pass pivoting technique); implementation of the primal-dual interior point method; implementation of the branch-and-bound procedure (based on the dual simplex method); application program interface (API). Please note that the current version of GLPK is tentative. Downloading GLPK GLPK distribution can be found on in the subdirectory /gnu/glpk/ on your favorite GNU mirror . For other ways to obtain GLPK, please read How to get GNU Software Documentation The documentation for GLPK is divided into the User's Guide and the Library Reference. The texinfo source for both of these are included in the main distribution file. Alternatively, already built Postscript versions can be found on in the same subdirectory as GLPK distribution. Mailing Lists/Newsgroups GLPK now has two mailing lists: and The main discussion list is , and is used to discuss all aspects of GLPK, including development and porting.

english - deutsch Visiting Professor, IFOR, ETH Zentrum, and on leave from University of Tsukuba, Tokyo, Japan Linear programming is an optimization problem, one of the simplest, mathematically. A standard formulation is to maximize a linear function c T x subject to a system of linear inequalities , where x is a variable n -vector, c and b are given n -vector and m -vector, and A is a given m × n matrix. The following figure illustrates a tiny example with n = 3 , where the set of feasible solutions forms a convex polytope in R Figur 1 Twenty years ago there was virtually no ambiguity in teaching a solving technique in standard Linear Programming lecture. We simply had to teach the simplex method [d-lpe-63], invented by G. Dantzig of Stanford University in 1951, period. Different geometric interpretations were perhaps the only sources of improvisation. In fact, it was widely believed that we could never beat the simplex method which then could already solve large-scale problems with several thousands variables and inequalities successfully. Now, every professor in charge of LP course is in a little trouble. The
