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
<m...@bahntechnik.de> for bug report.
Scripts to build GLPK with Microsoft Visual Studio 2015 were
added. Thanks to Xypron <xypron.g...@gmx.de> for contribution
and testing.
