GLPK 4.57 Release Information

Release date: November 08, 2015

GLPK (GNU Linear Programming Kit) is intended for solving large-scale
linear programming (LP), mixed integer linear programming (MIP), and
other related problems. It is a set of routines written in ANSI C89 and
organized as a callable library.

        In this release:

        A new, more efficient implementation of the dual simplex method
        was included in the package. This new implementation replaces
        the old one, which was removed.

        Option sr_heur was added to struct glp_iocp to enable/disable
        the simple rounding heuristic used by the MIP solver. Thanks to
        Chris Matrakidis <address@hidden> for suggestion.

        New API routine glp_at_error was added and documented. Thanks
        to Jeroen Demeyer <address@hidden> for suggestion.

        Some minor typos were corrected in the GLPK documentation.
        Thanks to Anton Voropaev <address@hidden> for typo

        An example application program TSPSOL was added. It uses the
        GLPK MIP optimizer to solve the Symmetric Traveling Salesman
        Problem and illustrates "lazy" constraints generation. For more
        details please see glpk/examples/tsp/README.
