30-day AMPL Trial
We offer a full-featured, unrestricted copy of AMPL with a trial license good for 30 days. To request a trial, fill out our trial license form. Return the completed form by fax to +1 425-940-6286 or email to fax@ampl.com.
The AMPL trial does not have a solver (optimizing algorithm) built in, but works with any solver — however obtained — that has an AMPL interface. Solvers that we sell directly are also available in trial versions, as described below. Links to other options may be found on our solver list.
30-day Solver Trials
Full-featured versions of solvers that we sell directly are also available under trial licenses:
- CONOPT, nonlinear
- CPLEX, linear & convex quadratic with mixed-integer
- Gurobi, linear with mixed-integer
- KNITRO, nonlinear with mixed-integer
- MINOS, linear & nonlinear
- SNOPT, nonlinear
To request trials for one or more of these solvers, list them on the Solvers line at the bottom of the trial license form. Trial versions of other solvers may be available from their developers; see our solver list.
Other Trial Options
Run some simple AMPL models online through our Try AMPL page.
Download a permanent “student” version of AMPL limited to 300 variables and 300 constraints plus objectives, after presolve — 500 for linear problems — by following the instructions on our downloads page. Student versions of some solvers are also available there.
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.
Special arrangements for demonstrations and workshops are also available. Write to info@ampl.com or call +1 773-336-2675 to discuss possibilities.
