Hans Mittelmann's Benchmarks for Optimization Software. For rigorous definitions and theory, which are beyond the scope of this document, the interested reader is referred to the many LP textbooks in print, a few of which are listed in the references section.

All these entities must have consistent dimensions, of course, and you can add "transpose" symbols to taste. The matrix A is generally not square, hence you don't solve an LP by just inverting A.

The word "Programming" is used here in the sense of "planning"; the necessary relationship to computer programming was incidental to the choice of name. Hence the phrase "LP program" to refer to a piece of software is not a redundancy, although I tend to use the term "code" instead of "program" to avoid the possible ambiguity.

Although all linear programs can be put into the Standard Form, in practice it may not be necessary to do so.

This allows a variable to be without an explicit upper or lower bound, although of course the constraints in the A-matrix will need to put implied limits on the variable or else the problem may have no finite solution.

Also, LP software can handle maximization problems just as easily as minimization in effect, the vector c is just multiplied by The importance of linear programming derives in part from its many applications see further below and in part from the existence of good general-purpose techniques for finding optimal solutions.

These techniques take as input only an LP in the above Standard Form, and determine a solution without reference to any information concerning the LP's origins or special structure. They are fast and reliable over a substantial range of problem sizes and applications.

Two families of solution techniques are in wide use today. Both visit a progressively improving series of trial solutions, until a solution is reached that satisfies the conditions for an optimum.

Barrier or interior-point methods, by contrast, visit points within the interior of the feasible region. These methods derive from techniques for non-linear programming that were developed and popularized in the s by Fiacco and McCormick, but their application to linear programming dates back only to Karmarkar's innovative analysis in The related problem of integer programming or integer linear programming, strictly speaking requires some or all of the variables to take integer whole number values.

Integer programs IPs often have the advantage of being more realistic than LPs, but the disadvantage of being much harder to solve. The most widely used general-purpose techniques for solving IPs use the solutions to a series of LPs to manage the search for integer solutions and to prove optimality.

Linear and integer programming have proved valuable for modelling many and diverse types of problems in planning, routing, scheduling, assignment, and design.

Industries that make use of LP and its extensions include transportation, energy, telecommunications, and manufacturing of many kinds. A sampling of applications can be found in many LP textbooksin books on LP modelling systemsand among the application cases in the journal Interfaces.

Thanks to the advances in computing of the past decade, linear programs in a few thousand variables and constraints are nowadays viewed as "small".

Problems having tens or hundreds of thousands of continuous variables are regularly solved; tractable integer programs are necessarily smaller, but are still commonly in the hundreds or thousands of variables and constraints.

The computers of choice for linear and integer programming applications are Pentium-based PCs and the several varieties of Unix workstations.This course will examine the theory and practice of cost accounting. Topics covered include cost accounting system, responsibility accounting, job order costing, process costing, variable costing, budgeting, cost variance, cost behavior analysis and decision-making processes.
