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 19 includes a number of significant enhancements and new features.
Databases are the tool of choice for managing large amounts of information. LINGO uses ODBC technology to allow you to access set information and data in virtually any popular Windows database application. Using a single statement in your model you can transfer data between LINGO and database applications such as:LINGO can be run as a server application from a database program. For example, using Microsoft Access as your development environment and LINGO as your solver, you could build a complete, turn-key database application for a client or colleague. The user could be provided with input screens, output screens and customized reports as well as a “Solve” button right in their application, which directly calls LINGO and runs a series of specified commands.
CAPACITY AND OPTIONS DETAILS:
|Linear Models||Nonlinear||Multistart||Global Solver|
|Capacity||Constraints||Variables||Integers||Variables||NL Variables||NL Variables|
|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. LINGO can exploit multiple CPU cores for faster model generation, … more
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, … more
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, … more
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, … more
|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, … more
Order of Magnitude Faster on Long Skinny Linear Models Enhancements to the Simplex Solvers allow significantly faster solution of linear models with many times more variables than constraints.
|ENHANCEMENTS TO THE QUADRATIC/CONIC SOLVERS
Models with ex and xk terms are solved faster — so called Barrier Solver exponential and power cones.
|FASTER WHEN SIMULTANEOUSLY SOLVING LPS USING DIFFERENT SOLVERS
An improved feature allows users to concurrently run the Primal Simplex, Dual Simplex, and Barrier solver each on a separate core ensuring the solution in the shortest time regardless of which solver is fastest.
|NUMEROUS GLOBAL SOLVER ENHANCEMENTS
Improved recognition and exploitation of convexity of various composite functions.
Improved performance for models with convex-concave functions.
Models with ratio/fractional objective, including MIP, solve an order of magnitude faster.
Substantial speed improvements on Non-convex Quadratically Constrained Quadratic Programs.
|INTEGER SOLVER IMPROVEMENTS
Better performance on many integer models has been achieved through improved selection of default settings for cut generation and solution heuristics.
Expanded capabilities for the All Different constraint type.
New feature to delete all members of a derived set.
There is a new function for building interactive applications that allows you to prompt the user for input at runtime.
More efficient use of user supplied starting point information for faster solution of integer models.
New features to facilitate building and debugging LINGO models embedded in Excel workbooks.
More efficient storage of Stochastic Programming scenarios allowing the solution of significantly larger stochastic models.
