Modeling and Optimization Systems

LINGO Author: LINDO Systems 1415 N. Dayton St., Chicago IL 60622 USA

LINGO combines a full featured modeling environment with a set of solvers for linear, integer, and nonlinear models. Beginning modelers will appreciate the easy, natural style of model expression and the comfortable Windows interface. Power modelers will love the option to use the advanced modeling language, library of mathematical functions, and the ability to read data from external files and spreadsheets.

Available for PC and (in Hyper and larger sizes) the following workstations: IBM, HP 9000, SunSPARC, Linux, Silicon Graphics, and DEC Alpha.

The Perfect Modeling Package

Imagine the perfect modeling package. It would allow you to express your problem quickly in a highly readable form, be able to store data and solution information in a variety of convenient ways, and be capable of solving a broad range of problems. LINGO just may be that perfect modeling package. It gives you all this and much more.

Powerful Modeling Environment

LINGO lets you express your most complex models in a simple, efficient manner. Formulate your model explicitly -- or use LINGO’s modeling language to represent it in mathematical notation with subscripted variables. This makes your model extremely compact and easy to read. Use LINGO’s extensive library of common mathematical, probability, and financial functions -- or you can create your own custom functions. LINGO even comes with a DLL that can be called from your own application.

Easy Data Handling

You won't have to wrestle with your data to get it in a form LINGO can accept -- LINGO allows you to keep your data in a variety of natural, convenient forms. You can choose to store your data in a database, spreadsheet, or simple text file, and, after solving the model, LINGO allows you to write the results directly in any of these forms. LINGO supports popular databases including Access, Oracle, DB/2, Paradox, and SQL Server as well as Excel and 1-2-3 spreadsheets.

Versatility - the LINGO Solvers

Versatile enough to be applied to a wide range of problems, LINGO is equipped with fast internal solvers for large scale linear and nonlinear models. You can even add binary and general integer restrictions to your problems. Also with LINGO, you never have to specify or load a separate solver, because LINGO reads your formulation and automatically selects the appropriate one.
