The GAMS Test Library

The GAMS Test model library was developed for testing and quality control, both for the GAMS base module and the many solvers distributed with the GAMS system. As such, it is designed and maintained to be used primarily by GAMS staff and our solver providers. However, users may find it useful as well.

You want all the details on the semantics of MCP models? See what is tested for by browsing and running the MCP models from testlib. Not sure what the convention on the sign of the marginal values is? Check the LP tests where all possible combinations are tested. You can not find an example of how utility XYZ is used? Search testlib: we have tests for most of the utilities we ship. In addition, users can run the GAMS quality tests on their own hardware in case of suspected bugs or system-dependent behavior.
