Frequently Asked Questions About Ordering

Is it necessary to order a solver? AMPL does not have any built-in solvers. Often it is convenient to order one of the popular solvers that we sell directly, but you can also choose from many other AMPL-interfaced solvers available for purchase or download from independent sources. AMPL automatically recognizes any compatible solvers on your system, and there is never a charge for a “solver link”.

Can payment be made by credit card? Yes, you need only give us an email address for the cardholder. We will then send a message to that address containing instructions for entering the credit card number through a secure web interface. (PayPal acts as our credit card processor for this transaction, and you will see their logo on the email, but there is no requirement that you register for their services.)

What is the license agreement for use of AMPL and solver software? By using the purchased software you agree to our Terms & Conditions governing the licensing and use of AMPL products. Contact us if your organization has special requirements for license agreements.
