GAMS User's Guide

This guide describes the main features of GAMS (the acronym stands for General Algebraic Modeling System) and explains how to use it. GAMS is designed to make the construction and solution of large and complex mathematical programming models more straightforward for programmers and more comprehensible to users of models from other disciplines, e.g., economists. Because it can make concise algebraic statements of models in a language that is easily read by both modelers and computers, GAMS can substantially improve the productivity of modelers and greatly expand the extent and usefulness of mathematical programming applications in policy analysis and decision making. GAMS was developed by Alexander Meeraus and Anthony Brooke at the World Bank.
