Frequently Asked Questions
Our standard AMPL license and the AMPL Community Edition license are the same in terms of power – no limitations on number of variables and constraints. The main difference is the required internet connection with the Community Edition and only connecting to commercial solvers for a 30-day trial.
Inside the license portal you can request an extension for your 30 day solver trial. This can often be extended to allow you to complete ongoing work or testing.
Our standard licenses have premium email, phone, and video support, while our Community Edition has basic email support and the user forum (where our development team frequently provides support).
As soon as you sign up through the license portal you can download your license and use it immediately. Your Community Edition license never expires.
Yes! There are limitations on commercial connectivity over 30 days, but it is a great place for modelers to prototype and share ideas, or use on projects needing only an open source solver (*reminder you need a continuous internet connection for license validation).
No. If you need to use a commercial solver for more than 30 days and you do not qualify for a professional or academic discount, you will need to purchase a standard AMPL license and your preferred commercial solver license. Contact us to get started or for further support.
