The following solvers (some with stricter limits as shown) are included in the demo packages: These limitations are applied after any presolve reductions and elimination of variables. For nonlinear problems, 300 variables and 300 constraints plus objectives.For linear problems, 500 variables and 500 constraints plus objectives.Your package includes a free license that permits unrestricted use for evaluation or study, subject to limits on the size of problem that can be sent to a solver: Command-line AMPL, which runs in a simple command window.The AMPL IDE, an integrated command processor and editor that assists in model development.In downloading this software, you agree to the Terms & Conditions governing free demo and trial versions of AMPL and solver products.ĭemonstration packages are available for your choice of AMPL modeling environments: Free AMPL and solver demos are licensed for evaluation and instructional use only.

Īs a full-featured 30-day trial version, for experimenting with AMPL and solvers on your optimization applications without any limitations as to problem size.
Also use this version to experiment with building your own models and solving small instances that fit within the size limitations (listed below).
