LINGO

LINGO is a powerful optimization modeling software designed to simplify and accelerate the development and solution of mathematical models. It supports a wide range of problem types including linear, nonlinear, integer, quadratic, stochastic, and global optimization. LINGO integrates a modeling language, development environment, and built-in solvers into a single package, making it ideal for analysts, researchers, and decision-makers across industries.

Features

• Intuitive Modeling Language: Express models using summations and subscripted variables in a readable, paper-like format.
• Integrated Solvers: Automatically selects and runs the appropriate solver for the model type, including simplex, barrier, nonlinear, global, and stochastic solvers.
• Data Connectivity: Imports and exports data directly from spreadsheets and databases for seamless integration.
• Interactive and Programmatic Use: Build and solve models interactively or call LINGO from external applications via DLL, OLE, or Excel macros.
• Multi-Core Processing: Utilizes multiple CPU cores for faster model generation and solution.
• Extensive Documentation: Comes with a comprehensive user manual and modeling textbook, plus dozens of sample models.

Capabilities

• Linear and Integer Programming: Solve large-scale LP and MIP problems with advanced preprocessing and cut generation.
• Nonlinear and Global Optimization: Use GRG, SLP, and branch-and-bound techniques to find local or global optima.
• Quadratic and Conic Models: Efficiently solve models with quadratic objectives or constraints, including SOCPs.
• Stochastic Programming: Model uncertainty with multistage stochastic optimization using Benders decomposition and deterministic equivalents.
• Model Reduction and Linearization: Automatically simplify models and convert nonsmooth functions into linear equivalents for faster solving.

Benefits

• Speed and Efficiency: Reduces development time and accelerates solution processes with built-in solvers and preprocessing.
• Flexibility: Handles a wide variety of optimization problems in a single environment.
• Ease of Use: Designed for both novice and expert users with intuitive syntax and extensive help resources.
