GLPK 4.52 Release Information
*****************************

Release date: July 18, 2013

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:

        The clique cut generator was essentially reimplemented, and now
        it is able to process very large and/or dense conflict graphs.

        A simple rounding heuristic was added to the MIP optimizer.

        Some bugs were fixed in the proximity search heuristic routine.
        Thanks to Giorgio Sartor <address@hidden>.

        New command-line option '--proxy [nnn]' was added to glpsol to
        enable using the proximity search heuristic.

        A bug (incorrect processing of LI column indicator) was fixed
        in the mps format reading routine. Thanks to Charles Brixko for
        bug report.
