LINDO automatically introduces slack or surplus variables to convert inequality constraints into equalities. The numbering of the rows starts with the number 1, as opposed to 0. Thus, ROW 1 refers to the objective-function row, ROW 2 refers to (functional) constraint (1), and so on; correspondingly.

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 in Portuguese (Brazilian) Now Available.
A collection of over 100 lectures, each of about 5 to 10 minutes in length has recently been made available on YouTube. These videos, in Portuguese, provide a very thorough introduction to the LINGO modeling system. 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, Business Administration undergraduate egress, who has worked with Prof Dr Silvia Araujo dos Reis and Prof Dr Victor Rafael R Celestino from Universidade de Brasilia (UnB). The videos are available at 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 programmingsolvers 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.

MIP problems can be extremely difficult to solve, though there are no steadfast rules on enhancing MIP performance, certain things may be advantageous in improving the performance on some models and be a hinderous on other problems. Below are some of the considerations one should look into when try to solve difficult MIP problems:

Lindo Programming

• Heuristic setting: LINDO has a number of heuristics that can be used to find initial integer feasible solutions, finding good solutions fast greatly benefits the subsequent brand and bound search process eliminating may 'bad' branches. For difficult problems one should try to set the heuristic level parameter ('MIPHeuristicLevel') to 3,4 or 5. Higher value settings will cause more time to be spent in the heuristic, which may not be worthwhile.

• Cuts: Addition of cuts helps eliminate non-integer feasible regions from the LP relaxed convex hull. This provides improved bounds during the branch and bound process. The option 'MIPCutLevel' which is a bit setting has a default value of 22526 which means 12 types of cuts are set out of 14. To include full cut generation one can set this value to 32766. The more cuts added, the larger the inherent matrix becomes which can increase the processing time at the nodes. However usually on difficult models an aggressive cut strategy is the best mode of practice.

The area of nonlinear programming is diverse, and there is no anyone method that can handle all types of NLPs unlike in linear programming. If the NLPs are large or are highly nonlinear in nature, utilizing the global optimizer will generally give bad performance. Models larger than 100 variables can be extremely difficult to solve to proven global optimality. Large models should use the local solver, MPL by default will use LINDO's local optimizer when solving NLP one has to specify the boolean option 'UseGlobalOptimizer' to activate the global solver. One can employ a multi-start methodology using the local solver to find better local optima, this naturally will increase the total solve time but should result in better solutions. Typically one should set a multi-start value of 4 or 5 (setting: 'NLPMaxLocalSearch').

For LPs LINDO will display the iteration number, the dual/primal objective value, iteration infeasibility and the time of the iteration.
