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 14.0 includes a number of significant enhancements and new features.
CAPACITY AND OPTIONS DETAILS:
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.
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, … more
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, … more
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, … more
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, … more
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, … more
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.
Improved heuristics for general integer programs.
Average performance improvement of 2-3% on our standard test set.
Improved method for generating all alternative optima to a linear program.
The first call to LSgetNextBestSol() creates a prespecified number of corner points via pivoting on the optimal solution set. Subsequent calls will nonredundantly return successive corner points. Standard solution query methods can be used to access primal-dual vectors following each call to LSgetNextBestSol.
Support for Indicator constraints, e.g., z = 0 implies x + y <= 0;
more expressions can be automatically linearized, so you can now use a fast linear solver where otherwise a much slower (30x?) nonlinear solver.might be required.
advanced linearization of QP and Conic models
improved linearization of certain IF expressions.
Nonlinear and Global solver:
faster (order of magnitude) solution of linear fractional programs (ratio objectives).
improved bound tightening process in preprocessing of nonlinear models.
auxiliary variables generated automatically to improve performance with complicated expressions.
Support for additional useful but “problematic” functions:
Power utility function (x^g-1)/g and the exponential ratio function (exp(g) – 1)/g, are important in some situations modeling consumer behavior. LINDO API can now robustly avoid the numerical problems that would otherwise occur when g approaches 0.
Julia/JuMP is now supported officially.
Python interface installations now easier via pip (pypi.org)
Matlab interface now has two alternative methods for linear and integer optimization, LSlinprog and LSintprog. Argument lists follow their counterparts, linprog and intprog, in Matlab’s optimization toolbox.
