Release date: Nov 14, 2003

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 in the form of a callable
library.

In GLPK 4.2:

• preliminary implementation of GLPK Integer Optimization Suite
  (IOS) was included in the package.
• new API routine lpx_print_sens_bnds contributed by Brady

  included. It is intended for bounds sensitivity analysis. This
  function is also available in the solver glpsol via –bounds
  command-line option.

  contributed by Chris Rosebrugh <cpr@pobox.com> was included.
• GLPK DELI (Delphi Interface) contributed by Ivo van Baren
