GLPK 4.30 -- Release Information
********************************
Release date: Aug 13, 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 core LP solver based on the primal simplex method was
re-implemented to allow its further improvements. Currently the
new version provides the same features as the old one, however,
it is a bit faster and more numerically stable.
Some changes were made in the MathProg translator to allow <,
<=, >=, and > on comparing symbolic values. Thanks to Heinrich
Schuchardt <address@hidden> for patches.
Internal routine set_d_eps in the exact LP solver was changed
to prevent approximation errors in case of integral data.
Thanks to Markus Pilz <address@hidden> for bug report.
See GLPK web page at <http://www.gnu.org/software/glpk/glpk.html>.
GLPK distribution can be ftp'ed from <ftp://ftp.gnu.org/gnu/glpk/> or
