AMPL is an exceptionally powerful and natural tool for developing and deploying the complex optimization models that arise in diverse business and engineering applications. AMPL’s modeling language lets you formulate problems the way you think of them, while the AMPL interactive development system supports all of the best large-scale solvers to help you find good solutions fast. AMPL also features an integrated scripting language for automating analyses and building iterative optimization schemes; application programming interfaces for embedding your models within enterprise systems; and alternatives for deploying AMPL models as web-based collaborative decision-making tools.
