Lindo

LINDO is used at thousands of businesses, colleges, universities and government agencies around the world. It's the convenient but powerful tool for solving linear, integer, and quadratic programming problems. Specific application areas where LINDO has proven to get the BEST would include product distribution, ingredient blending, production and personnel scheduling, and inventory management.

Friendly for Beginners

The guiding design philosophy for LINDO has been that is a user wants to do something simple, then there should not be a large setup cost to learn the necessary features of LINDO. If you're a novice, you'll appreciate how easy it is to learn. Problems can be quickly and easily entered within LINDO or imported from text files created in your favorite word processor. LINDO/PC even includes its own full-screen editor for small problems and a pop-up window to track the progress of your problem while it's optimizing. You can interrupt optimization at any point and get the best answer so far. Also, LINDO provides clear, useful on-line help for all commands, so you can learn as you build your model. The User's Manual thoroughly explains LINDO's commands and features. We even include a textbook full of detailed examples and modeling techniques.

Powerful for Professionals

LINDO recognizes general integer variables (not just 0/1), free variables, and bounded variables, and has a comprehensive set of over 50 commands for data input, editing, optimization, display, logical data inquiry, file handling, and sensitivity analysis. MPS and FORTRAN interfaces simplify entering large problems, and LINDO lets you perform Lexico-optimization, a form of goal programming. Developers will want to exploit LINDO's flexibility by adding custom commands, linking in your own routines, or using the LINDO engine to run your own vehicle.
