General information

The GAMS Base Module includes the GAMS Language Compiler, GAMS-APIs, and many utilities . All solvers are included in the system and can be used with size limitations. To remove those limitations, you can purchase licenses for individual solver components from us. The GAMS End User License Agreement governing the use of the software is available on our website.

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.

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 purchase a separate license from the solver vendor before the solver can be used. Using GAMS/Solver-Links, including the Open Solver Interfaces to commercial solvers, requires confirmation that the user has 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.

Detailed information about the solvers, their availability on the supported platforms, and the model types they are capable of solving are available at this link . Please contact us for a free evaluation license, if you would like to try different solvers.

Available Licenses

Named user licenses

GAMS licenses are based on the total number of individual GAMS users within an organizational unit. Individual licenses cannot be shared between users. Any GAMS user is welcome to install GAMS on more than one computer of the same platform - assuming that only one of those machines will be used at a time.

GAMS installations may be used both for development and deployment. We impose no limitations with regards to the number of CPUs or memory, but in general user based licenses are to be used for interactive sessions only, i.e. GAMS has to be called either via Studio or interactively via the command line. If GAMS is called by the licensee through external applications or scripts, a limitation to one concurrent job shall apply.

Single User Licenses are restricted to an individual person - the license file will show the name and the email address. We provide multi-copy discounts for additional single-user licenses on the same platform: 30% discount on the original price for the second copy, and 50% discount for the third and following copies of the same modules. These discounts apply as long as the other license(s) are under maintenance (see below).

Multi-User/Department (MUD) Licenses allow several users to run the licensed software on one or more computers with the same operating system. MUD licenses are available to departments, work-groups, or project teams where the license is centrally administered. The license file will show the name and the email address of the license administrator.

License Users Price
small MUD up to 5 twice the price of a single user system
medium MUD up to 10 three times the price of a single user system
large MUD up to 20 four times the price of a single user system

Machine based licenses

If our named user licenses do not fit your use case, please do not hesitate to contact us to discuss machine based licensing options.

Optional License Add-Ons

Cross-Platform Licenses: Any license can be made a cross-platform (generic) license at an additional charge of 50% of a single user price for all licensed modules.

Package discounts

NLP Package: CONOPT, IPOPTH, KNITRO, MINOS, SNOPT are discounted 25% if two or more are purchased.

GLOBAL Package: ANTIGONE, BARON, GLOMIQO, LGO, LINDOGLOBAL, and MSNLP are discounted 25% if two or more are purchased.

License duration

Our standard license fee covers a perpetual license to use the software. Maintenance and support (M&S) is free during the first year after the purchase of the software. After the first year, the optional annual fee for M&S is 20% of the list price for all licensed modules. M&S allows free updates, adding components, platform switching without additional charge, and multi-copy discounts on the same platform. Up to four changes per year of the name on a user-based license are included. If the user does not purchase M&S for some period and chooses to purchase it at a later date, we will charge the prevailing annual maintenance and support fees for the periods that were not covered.

Additional License Options

For certain modules and solvers we offer additional license options

  • Subscription based licenses on an annual basis or for extended durations
  • Customized licenses that cover the usage of GAMS and specific solvers in an application or a cluster
  • Licenses for Cloud Based Burst Computing

Please contact us if you would like to discuss these or additional requirements.
