Frequently Asked Questions

For more answers to your questions, contact our team, or join our Discourse Forum.

Can I test AMPL before making a purchase?

Yes! Download and start using the AMPL Community Edition, start a 30-day full trial or get your size-limited demo

How can I compare AMPL to other modeling languages?

Compare AMPL to other modeling languages on the NEOS server. Learn more here.

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. (Square 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.)

AMPL maintenance and support service includes access to AMPL and solver software updates, regeneration of license files necessitated by hardware changes, and technical assistance with installation and execution. The quoted ”Purchase + Maintenance” prices include one year of maintenance and support. Subsequent maintenance and support service is charged at an annual rate equal to a percentage, currently 20%, of the license price in effect at the time of renewal.

Maintenance and support is billed annually unless cancelled by you prior to the renewal date. Contact sales@ampl.com for information on upgrades to licenses not currently under maintenance.

How can I learn more about individual solvers?

As listed above, we offer many popular solvers for direct purchase; refer to Solvers We Sell to learn more, including problem types supported and methods used.

What is included in a solver purchase?

Our prices for these solvers apply to the versions that incorporate an AMPL interface; a previously or concurrently purchased copy of the AMPL software is needed to use these versions. Programming libraries and other forms of these solvers are not included.

Is it necessary to purchase a solver?

All open-source solvers are automatically included with AMPL. Only commercial solvers need to be purchased.

Can I purchase AMPL only and use it with a solver I obtain from another vendor?

In general, solvers with an AMPL interface work with AMPL. AMPL only guarantees proper functionality for solvers that were obtained from AMPL directly or one of our official partners.

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.

If I start using a free license and then purchase AMPL later, how do I make the switch?

All that is needed is to switch out the license file our sales team sends you. There is no need to install a new AMPL binary.
