LINDO (Linear, Interactive, and Discrete Optimizer) is a software package for linear programming, integer programming, nonlinear programming, stochastic programming and global optimization.

Enables user to easily create their own optimization applications. It allows user to plug the power of the LINDO solvers right into customized applications and mathematical programs that have written. The recently released LINDO API 11.0 includes a number of significant enhancements and new features. The LINDO API allows application developers to easily create customized programs that call LINDO’s fast set of linear and integer solvers. It includes dozens of routines to formulate, solve, query, and modify optimization problems and gives the user access to greater speed and algorithmic control than any other product offered by LINDO.

II. “What’sBest!” – add-in for linear, integer and nonlinear optimization.
What’sBest! is the Spreadsheet Solver. First released for Lotus 1-2-3 and later also for Microsoft Excel. What’sBest! solves linear, nonlinear, and integer models in today’s most popular tool for modeling business problems–the spreadsheet. What’sBest! is a natural extension of Microsoft Excel, allowing spreadsheet users to begin optimization modeling almost immediately. Models are easy to build and understand in a free form layout using standard spreadsheet equations.

  • Fast, Easy Application Development
  • The LINDO API makes it easy for you to seamlessly integrate optimization into your own application. The developer interface has been designed for maximum ease-of-use and flexibility. It comes with clear, comprehensive documentation and examples to help you get running quickly.

  • Powerful Solvers
  • LINDO API provides you with an arsenal of powerful solvers for Stochastic, Linear, Nonlinear (convex & nonconvex/Global), Quadratic, Quadratically Constrained, Second Order Cone and Integer optimization. All solvers incorporate numerous enhancements for maximum speed and robustness.

  • Convenient Interface to MATLAB
  • The Windows 32 bit and 64 bit versions of LINDO API can be run as a MATLAB callable function. Using MATLAB ‘s modeling and programming environment, you can build and solve models and create custom algorithms based upon the LINDO API’s routines and solvers.

  • Extensive Documentation and Help
  • LINDO API provides all of the tools you will need to get up and running quickly. You get the LINDO API User Manual (in printed form and available online in pdf format) that includes detailed function definitions for all routines. Also included in the manual is a discussion to assist you in writing your own applications.

  • Analyze Infeasible and Unbounded Models
  • LINDO API includes tools that allow you to track down what has caused a model to be infeasible or unbounded. The tools isolate a portion of the original model as the source of the problem. This allows you to focus your attention on a relatively small subsection of the model to look for formulation or data entry errors. On infeasible linear, nonlinear, quadratic and integer models, the tools can find an irreducibly inconsistent set of constraints (IIS), and on unbounded models, the tools can find an irreducibly unbounded set of columns (IUS).

  • Create Web and Intranet Applications
  • The LINDO API is thread safe to allow you to create web and network applications that handle multiple user sessions concurrently. Web and network applications require special licensing. Contact LINDO Systems for more information.

  • Model Size Flexibility
  • Why pay for more capacity than you need? The LINDO API is available in a variety of different capacities. The capacities range from a few hundred variables to versions with unlimited capacity, so you can select the product that best suits your needs for a particular problem.


  • The World’s Most Powerful Solver for Microsoft Excel
  • What’sBest! will efficiently solve your biggest, toughest models. The linear, integer, nonlinear and global solvers in What’sBest! have been designed for large scale commercial use and field tested on real world models by companies around the world. For optimization modeling in Excel, What’sBest! offers unrivaled speed and capacity.

  • Build Models for your Clients
  • What’sBest! is an ideal tool for creating optimization applications for use by others. What’sBest! allows you to provide the application in a form that is best suited to the user. For managers, you can build a simple, easy-to-understand spreadsheet. For clerical workers, you can create turn-key applications with custom interfaces.

  • Extensive Documentation and Help
  • What’sBest! provides all of the tools you will need to get up and running quickly. You get the What’sBest! User Manual (in printed form and available via the online Help) that fully describes the commands and features of the program. Also included in the manual is discussion of the major classes of linear, integer and nonlinear optimization problems along with over two dozen real world based examples that you can modify and expand.
