GLPK 4.60: Some improvements were made in the primal and dual simplex solvers to make the solution process more numerically stable. An experimental long-step ratio test feature was added to the dual simplex. On API level this feature is available thru the GLP_RT_FLIP option. For glpsol it is available thru the options --flip (for MIP) or --flip and --dual (for LP). This feature is not documented yet. Additional check was added to reject wrong solutions sometimes reported by the PROXY heuristic. A bug (memory leak) was fixed in the FPUMP heuristic routine. The header sql.h was renamed to avoid conflicts with standard ODBC headers.
