The XPRESS Library is a collection of math programming models (LP and MIP) from XPRESS Model Library (Examples). The GAMS models were translated by Andre Savistky as is from the original XPRESS source. For questions or comments, he can be reached via email. The raw GAMS models were converted into GAMS scalar format using the CONVERT facility. For models with multiple solves, only the first solve instance is translated.
