GLPK 4.33 -- Release Information

Release date: Oct 30, 2008

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 C and
organized as a callable library.

In this release:

        The following new API routines were added to the package:
        glp_copy_prob         copy problem object content
        glp_exact             solve LP in exact arithmetic
                              (makes lpx_exact deprecated)
        glp_get_unbnd_ray     determine variable causing unboundedness
                              (makes lpx_get_ray_info deprecated)
        glp_interior          solve LP with interior-point method
                              (makes lpx_interior deprecated)

        The following new API routines for processing models written in
        the GNU Mathprog language were added to the package:
        glp_mpl_alloc_wksp    allocate the translator workspace
        glp_mpl_read_model    read and translate model section
        glp_mpl_read_data     read and translate data section
        glp_mpl_generate      generate the model
        glp_mpl_build_prob    build LP/MIP instance from the model
        glp_mpl_postsolve     postsolve the model
        glp_mpl_free_wksp     deallocate the translator workspace
        (These routines make lpx_read_model deprecated.)

        For description of all these new API routines see the reference
        manual included in the distribution.

        A crude implementation of CPLEX-like interface to GLPK API was
        added to the package. Currently it allows using GLPK as a core
        LP solver for Concorde, a well known computer code for solving
        the symmetric TSP. For details see examples/cplex/README.

        Some bugs were fixed in the SQL table driver. Thanks to Xypron
