General algebraic modeling system
open-in-new
<p>The general algebraic modeling system (GAMS) is a high-level <a href="/facts/Computer_model/Re6o8vzN">modeling</a> system for <a href="/facts/Optimization_(mathematics)/oRn8Iv5I">mathematical optimization</a>. GAMS is designed for modeling and solving <a href="/facts/Linear_optimization/GduXFQxT">linear</a>, <a href="/facts/Nonlinear_optimization/cSXGuX2m">nonlinear</a>, and <a href="/facts/Mixed_integer_programming/GduXFQxT">mixed-integer optimization</a> problems. The system is tailored for complex, large-scale modeling applications and allows the user to build large maintainable models that can be adapted to new situations. The system is available for use on various computer platforms. Models are <a href="/facts/Software_portability/tWKVGCBb">portable</a> from one platform to another. </p><p>GAMS was the first <a href="/facts/Algebraic_modeling_language/0IXq6kFg">algebraic modeling language</a> (AML) and is formally similar to commonly used <a href="/facts/Fourth-generation_programming_language/QHUEG2IQ">fourth-generation programming languages</a>. GAMS contains an <a href="/facts/Integrated_development_environment/jbEINSQf">integrated development environment</a> (IDE) and is connected to a group of third-party optimization <a href="/facts/Solver/S8LurhlM">solvers</a>. Among these <a href="/facts/Solver/S8LurhlM">solvers</a> are <a href="/facts/BARON/RJkUmthX">BARON</a>, <a href="/facts/COIN-OR/we1fYPNj">COIN-OR</a> solvers, CONOPT, COPT Cardinal Optimizer, <a href="/facts/CPLEX/SnfwWLtb">CPLEX</a>, DICOPT, <a href="/facts/IPOPT/EdoDsb0Y">IPOPT</a>, <a href="/facts/MOSEK/zfmWsyqy">MOSEK</a>, <a href="/facts/SNOPT/Jg7Xrr6d">SNOPT</a>, and <a href="/facts/FICO_Xpress/mEFKqwEG">XPRESS</a>. </p><p>GAMS allows the users to implement a sort of <a href="/facts/Hybrid_algorithm/mgL7jc0c">hybrid algorithm</a> combining different solvers. Models are described in concise, human-readable algebraic statements. GAMS is among the most popular input formats for the <a href="/facts/NEOS_Server/qhUVshAf">NEOS Server</a>. Although initially designed for applications related to economics and <a href="/facts/Management_science/GVfa43B6">management science</a>, it has a community of users from various backgrounds of engineering and science. </p>
