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.

  • preliminary implementation of GLPK Integer Optimization Suite (IOS) was included in the package.
  • new API routine lpx_print_sens_bnds contributed by Brady Hunsaker <hunsaker@engr.pitt.edu> was included. It is intended for bounds sensitivity analysis. This function is also available in the solver glpsol via --bounds command-line option.
  • improved version of GLPK JNI (Java Native Interface) contributed by Chris Rosebrugh <cpr@pobox.com> was included.
  • GLPK DELI (Delphi Interface) contributed by Ivo van Baren <i.van.baren@freeler.nl> was included.
