There are some mailing lists, which will inform you about forthcoming releases, provide additional information, and are useful for questions about GAMS and modeling issues.

Without a valid GAMS license the system will operate as a free demo system with these limitations:

Model limits:

Number of constraints and variables: 300
Number of nonzero elements: 2000 (of which 1000 nonlinear)
Number of discrete variables: 50 (including semi continuous, semi integer and member of SOS-Sets)

Global solver limits:

Number of constraints and variables: 10

The GAMS log will indicate that your system runs in demo mode:
