AMPL can then switch to your solver, set up its algorithmic options, send it a problem to be solved and retrieve the results, all in the same way that you work with currently supported solvers. See our instructions on for further details. Linear simplex : Linear objective and constraints, by some version of the simplex method.

Linear interior : Linear objective and constraints, by some version of an interior or barrier method. Network: Linear objective and network flow constraints, by some version of the network simplex method.

Quadratic: Convex or concave quadratic objective and linear constraints, by either a simplex-type or interior-type method. Nonlinear: Continuous but not all-linear objective and constraints, by any of several methods including reduced gradient, quasi-newton, augmented lagrangian and interior-point.

Unless other indication is given see below , possibly optimal over only some local neighborhood. Nonlinear convex: Nonlinear with an objective that is convex if minimized or concave if maximized and constraints that define a convex region.

Guaranteed to be optimal over the entire feasible region. Nonlinear global: Nonlinear but requiring a solution that is optimal over all points in the feasible region. Complementarity: Linear or nonlinear as above, with additional complementarity conditions. Integer linear: Linear objective and constraints and some or all integer-valued variables, by a branch-and-bound approach that applies a linear solver to successive subproblems. Integer nonlinear: Continuous but not all-linear objective and constraints and some or all integer-valued variables, by a branch-and-bound approach that applies a nonlinear solver to successive subproblems.

Vendor or Download Site. Sources of further information for obtaining and using the solver. The following solvers some with stricter limits as shown are included in the demo packages:.

Consult the Solvers We Sell page or follow the individual links above for more solver information. To get started, follow the download instructions below for Windows , Linux , or macOS. Subject to the problem size limits given above, it supports all AMPL modeling features; it is compatible with all of the examples in the AMPL book , which is also freely downloadable.

When the time comes to try AMPL on larger problems than the demo version will permit, consider one of the following options, which are not subject to size limitations:. Your demo download can be converted to a free day trial by filling out the form on our Request a Full Trial page or for students, our AMPL for Students page.

As soon as your request is approved, we will email you a trial license file to replace the demo license that came with your download. The packages time out after the course is over. For large-scale research and commercial projects you can purchase AMPL and solvers under a variety of licensing arrangements. To install: Download the distribution zipfile, amplide. Double-click the zipfile icon, or apply an unzip utility, to extract the folder named amplide.

This will be your AMPL folder; optionally you may rename it and you may move it to any convenient location on your computer. To run: Inside your AMPL folder, double-click the amplide folder icon to open that folder, and then double-click the amplide. To install: Download the distribution zipfile, ampl. Double-click the zipfile icon, or apply an unzip utility, to extract the folder named ampl. Then you will see an ampl: prompt and can proceed to type AMPL commands.

Be sure to choose a solver, by giving a command of the form option solver xxx; with xxx replaced by the name of the solver that you wish to run. To install: Download one of the distribution archives, amplide. Then extract the contents of this archive by typing the command. When the extraction is complete you will see a directory named amplide.
