Solvers and Solver-Links

• A GAMS/Solver connects the GAMS Base Module to a particular solver and includes a license for this solver to be used through GAMS. It is not necessary to install additional software, as all of the listed solvers are already included in the installation package and licensed via the same method as GAMS/Base.

• A GAMS/Solver-Link connects the GAMS Base Module to a particular solver but does not include a license for the solver. It may be necessary to install additional software before a solver-link can be used. Use of any GAMS/Solver-Link requires written confirmation that all users have a valid license agreement for using the current version of the solver library and that the use of the solver will comply with the terms of that license agreement.

License Types

Our standard licenses are perpetual named single-user licenses, created to run on a local (on-premises) PC by the licensee. When ordering a license, please let us know your operating system of your choice (Win, Mac, or Linux). They include maintenance and support for the first 12 months after purchase.

If you require something different, we have a lot of flexibility to provide you with a solution that fits your needs:

• We can make any license cross-platform for an extra fee, so it can be installed on different operating systems.
• Subscription licenses are available for 50% off the regular price. These licenses expire automatically after 12 months.
• Machine Based licenses are available, which allow installation of GAMS on central compute resources. These can be used by an unlimited number of users (pricing will depend on the number of CPU cores in this case).
• For certain modules and solvers we offer additional license options such as application specific licenses.
• Multi-User/Department (MUD) Licenses are bundles of single user licenses available at a discount. A MUD license is available to departments, work-groups, or project teams where the license is centrally administered. Each license file will show the names and email addresses of the license administrator and of the licensed user.

Contact us at sales@gams.com if you would like to discuss these or additional license requirements.

Maintenance and Support (M&S)

M&S allows free updates, adding components to existing systems, platform switching without additional charge, and multi-copy discounts on the same platform. Up to four changes per year of the name of the licensee are included. The annual fee for M&S is 20% of the list price for all licensed modules. M&S is optional and not required. If the user does not purchase M&S for some period and chooses to purchase it at a later date, we will back-charge M&S fees for the periods that were not covered at the current list price.

Multi-Copy Discounts

The following discounts apply: 30% discount on the original price for the second copy, and 50% discount for the third and following copies of the same modules. Discounts apply as long as the other license(s) are under maintenance, and the additional licenses run on the same type of platform as the original system.

For machine based-licenses, a discount of 30% applies to the first increment of 12 cores beyond the first 12 cores, and 50% for each additional 12-core increment. Smaller increments are also available: please contact us for a quote.
