GLPK 4.56 Release Information

Release date: October 1, 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 and more robust implementation of the
        primal simplex method was included in the package. This new
        implementation replaces the old one, which was removed.

        A bug was fixed in the basis factorization routine. (The bug
        appeared if the basis matrix was structurally singular having
        duplicate row and/or column singletons.) Thanks to Martin Jacob
        <address@hidden> for bug report.

        Scripts to build GLPK with Microsoft Visual Studio 2015 were
        added. Thanks to Xypron <address@hidden> for contribution
        and testing.
