New versions of  What'sBest! 19, LINGO 21 and LINDO® API 15 are now available:


We are proud to release new versions with a number of significant features and enhancements.

What'sBest! 19: Learn about the new features  and download a limited capacity version.  
LINGO 21: Learn about the new features  and download a limited capacity version.  
LINDO® API 15: Learn about the new features  and download a limited capacity version.  

What's new:

 
Announcing  New  ARM / M Series Versions of LINDO API.
You can now download version 14 of the LINDO API that runs in native mode on ARM processers such as the M series on Apple Mac computers.  This native mode version is noticeably faster than the equivalent version running in emulated mode on the M series.  
More generally, the ARM / M series hardware is particularly attractive on  notebook computers because of its low power usage.  Its speed is nevertheless competitive with other hardware in the same price range.

Awarding Winning Work Uses Stochastic Optimization Capabilities of LINGO Software
At the IX National Congress of the Mexican Society for Operations Research, 13 - 15 Oct 2021, José Emmanuel Gómez Rocha, a student at Universidad Autonoma del Estado de Hidalgo, Mexico received the first-place award for the best thesis in the Undergraduate category, with his thesis "Optimization Models Multi-State Stochastics Applied to the Planning of the Production of a Furniture Company.” The work was directed by Prof. Héctor Rivera Gómez and Prof. Eva Selene Hernández Gress.
In his thesis, Gómez Rocha helped a furniture manufacturing company located in the state of Hidalgo, Mexico deal with the problem of how to set mean capacity as well as production levels in the face of uncertain demand when planning production over multiple periods. He used the stochastic optimization capabilities of the LINGO modeling software provided by LINDO Systems. In his work he did extensive analysis of what were the key features that affected expected profit. He looked at things such as is there a big difference between approximating random demand by a three-point distribution vs. a Normal distribution, or using a simple deterministic model as opposed to a model that takes into account uncertainty.

LINDO® products and pandemic models.

LINDO has recently added several models in its MODELS library devoted to modeling pandemics. Learn more.

LINDO adds a Beta version of LINDO® API for Android based hand held devices.
This version offers LINDO API to Android developers who want to incorporate LINDO’s powerful optimizers to their Android applications.
We also include a simple Android application for entering and solving linear, nonlinear and integer optimization models.

YouTube Introduction to LINGO and What'sBest! in Portuguese (Brazilian) Now Available. A collection of over 140 lectures, each of about 5 to 20 minutes in length has recently been made available on YouTube. These videos, in Portuguese, provide a very thorough introduction to the LINGO modeling system and What's Best! add-in to Excel. They start with the very elementary, such as transportation and staff scheduling problems, surplus/slack variables, and proceed to cover the more advanced features of LINGO, including K-best solutions and concepts such as convexity and positive definiteness. The videos have been prepared by Flavio Araujo Lim-Apo a master's student in Production Engineering at DEI/PUC-Rio, who has worked with Prof Dr Silvia Araujo dos Reis and Prof Dr Victor Rafael R Celestino from Universidade de Brasilia (UnB). The Lingo's playlist is available here and the What's Best's playlist is available here.

LINDO Systems has added a new, extensive "How to" modeling document to its library. An extensive collection of problems is presented and then modeled in LINGO. Just a few of the problem types described and modeled are: Agriculture, Assembly Line Balancing, Aviation, Blending/Diet, Clinics, Construction, Cutting, Energy, Fertilizer, Finance, Investment, Logistics, Metallurgy, Refinery, Scheduling, and Transportion. The exercises are complete in that they show not only how to prepare the model but also how to use the various features of LINGO to generate easy to understand reports based on the solutions to the models. This large document is the work product of the energetic Carlos Moya Mulero. He has had many years of experience in Operations Management at Volkswagen and elsewhere.

Speed and ease-of-use have made LINDO Systems a leading supplier of software tools for building and solving optimization models


LINDO® linear, nonlinear, integer, stochastic and global programming solvers have been used by thousands of companies worldwide to maximize profit and minimize cost on decisions involving production planning, transportation, finance, portfolio allocation, capital budgeting, blending, scheduling, inventory, resource allocation and more.
