OPTIMIZATION www.gams.com High-Level Modeling The General Algebraic Modeling System (GAMS) is a high-level modeling system for mathematical programming problems. GAMS is tailored for complex, large-scale modeling applications, and allows you to build large maintainable models that can be adapted quickly to new situations. Models are fully portable from one computer platform to another. State-of-the-Art Solvers GAMS incorporates all major commercial and academic state-of-the-art solution technologies for a broad range of problem types. GAMS Integrated Developer Environment for editing, debugging, solving models, and viewing data. PAVER 2: The next generation of the GAMS Performance Tools PAVER 2 automates the analysis and comparison of solver performance data. The use of the Python Data Analysis Library (http://pandas.pydata.org/) ensures platform independence, simple use, high performance, and flexibility. PAVER 2 highlights: • Easy customization of performance metrics • Computation and visualization of performance statistics • Automated handling of inconsistent solver outcomes • Integration with GAMS/EXAMINER solution point analyzer Europe GAMS Software GmbH [email protected] USA GAMS Development Corporation [email protected] http://www.gams.com PAVER 2 is open-source and available at: http://www.gamsworld.org/performance/paver2/
