Optimization Modeling

An Overview of the LINDO API:

With the LINDO API, you can easily create your own optimization applications. It allows you to plug the power of the LINDO solvers right into customized applications and mathematical programs that you have written. The recently released LINDO API 7.0 includes a number of significant enhancements and new features. .

Key Benefits of the LINDO API:

• 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), quadratic, quadratically constrained, second order cone and integer optimization. All solvers incorporate numerous enhancements for maximum speed and robustness.

• New Stochastic Programming Features

- LINDO Systems has begun shipping a new release of LINDO API that includes new features to allow users to incorporate uncertainty into their optimization models.

• Comprehensive Set of Routines

- Whether your application is big or small, simple or complex, the LINDO API provides the flexibility and functionality that you'll need. It includes dozens of routines to formulate, solve, query, and modify your problems.

• 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.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.

LINGO is a comprehensive tool designed to make building and solving Linear, Nonlinear (convex & nonconvex/Global), Quadratic, Quadratically Constrained, Second Order Cone, Stochastic, and Integer optimization models faster, easier and more efficient. LINGO provides a completely integrated package that includes a powerful language for expressing optimization models, a full featured environment for building and editing problems, and a set of fast built-in solvers. The recently released LINGO 13.0 includes a number of significant enhancements and new features.

Key Benefits of LINGO

Easy Model Expression -LINGO will help you cut your development time. It lets you formulate your linear, nonlinear and integer problems quickly in a highly readable form. LINGO's modeling language allows you to express models in a straightforward intuitive manner using summations and subscripted variables -- much like you would with pencil and paper. Models are easier to build, easier to understand, and, therefore, easier to maintain.

Convenient Data Options -LINGO takes the time and hassle out of managing your data. It allows you to build models that pull information directly from databases and spreadsheets. Similarly, LINGO can output solution information right into a database or spreadsheet making it easier for you to generate reports in the application of your choice.

Powerful Solvers - LINGO is available with a comprehensive set of fast, built-in solvers for Linear, Nonlinear (convex & nonconvex/Global), Quadratic, Quadratically Constrained, Second Order Cone, Stochastic, and Integer optimization. You never have to specify or load a separate solver, because LINGO reads your formulation and automatically selects the appropriate one.

Model Interactively or Create Turn-key Applications -You can build and solve models within LINGO, or you can call LINGO directly from an application you have written. For developing models interactively, LINGO provides a complete modeling environment to build, solve, and analyze your models. For building turn-key solutions, LINGO comes with callable DLL and OLE interfaces that can be called from user written applications. LINGO can also be called directly from an Excel macro or database application.

Extensive Documentation and Help -LINGO provides all of the tools you will need to get up and running quickly. You get the LINGO User Manual (in printed form and available via the online Help), which fully describes the commands and features of the program. Also included with super versions and larger is a copy of Optimization Modeling with LINGO, a comprehensive modeling text discussing all major classes of linear, integer and nonlinear optimization problems. LINGO also comes with dozens of real-world based examples for you to modify and expand.
