We offer a full-featured, unrestricted copy of AMPL with a trial license good for 30 days. If you are evaluating AMPL for purchase or for use in the AMPL for Courses program, request a trial by scrolling down to our online trial request form on this page. If you are a student then see instead our AMPL for Students page and the trial form there.
You can include any or all of the solvers we sell as part of your 30-day trial:
The AMPL 30-day trial also works with any other solver that has an AMPL interface. A range of free solvers for AMPL are available for download from our open-source solvers page. Trial versions of additional solvers may be obtained from their developers; links to further information are provided in our complete solver list for AMPL.
Run some simple AMPL models online through our Try AMPL Online page.
Download a permanent “demo” version of AMPL limited to 300 variables and 300 constraints plus objectives, after presolve — 500 for linear problems — by following the instructions on our Download a Demo Version page. Versions of some solvers are also included.
Run larger problems online using some of the many solvers available through the NEOS Server. Send AMPL model, data, and script files to be run online with the solvers, or use a local copy of AMPL to run online solvers through NEOS’s Kestrel interface.
If you are teaching a class, you may request time-limited but otherwise unrestricted bundles for distribution to students, through the AMPL for Courses program. Special arrangements for demonstrations and workshops are also available; write to email@example.com or call +1 773-336-AMPL to discuss possibilities.
Students please see our AMPL for Students page and use the form there instead.
