The AMPL system supports the entire optimization modeling lifecycle — formulation, testing, deployment, and maintenance — in an integrated way that promotes rapid development and reliable results. Using a high-level algebraic representation that describes optimization models in the same ways that people think about them, AMPL can provide the head start you need to successfully implement large-scale optimization projects.

AMPL integrates its modeling language with a command language for analysis and debugging, and a scripting language for manipulating data and implementing optimization strategies. All use the same concepts to promote streamlined model-building.

When you reach the stage of embedding your optimization models into applications and deploying them in enterprise systems, AMPL’s APIs for C++, C#, Java, MATLAB, Python, and R insure that you have a reliable and maintainable implementation.
