lpi_xprs.c File Reference Detailed DescriptionLP interface for Xpress-MP. This interface was revised for Xpress 26. Therefore, we removed all legacy code. Xpress requires that column and row names are unique. Since column and row names are not needed we ignore all column and row names to avoid the uniqueness issue.
