GLPK 4.22 -- Release Information

Release date: Sep 19, 2007

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.

        This is a maintainer release.

        A bug was fixed in the MIP preprocessor (ios_preprocess_node).
        Thanks to Roberto Bagnara <address@hidden> (Department of
        Mathematics, University of Parma, Italy) for the bug report.

        A bug was fixed in the MIP preprocessor (col_implied_bounds),
        due to which constraint coefficients with small magnitude could
        lead to wrong implied bounds of structural variables.

        A similar bug was fixed in the routine reduce_bounds.

        A bug was fixed in the routines glp_set_mat_row and
        glp_set_mat_col. (The bug appeared due to incorrect removing
        zero elements from the row/column lists.)

        A bug was fixed in the API routines lpx_read_mps and
        lpx_read_freemps, due to which bounds of type LI specified in
        BOUNDS section were incorrectly processed.

        A call to standard function vsprintf was replaced by a call to
        vsnprintf for security reasons. Many thanks to Peter T. Breuer
        <address@hidden> and Rafael Laboissiere <address@hidden>.
