-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 GLPK 4.23 -- Release Information ********************************
Release date: Oct 28, 2007 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 following new API routines were added: glp_read_sol read basic solution from text file glp_write_sol write basic solution to text file glp_read_ipt read interior-point solution from text file glp_write_ipt write interior-point solution to text file glp_read_mip read MIP solution from text file glp_write_mip write MIP solution to text file For description of these routines and corresponding file formats see Chapter "API Routines", Section "Utility routines" in the reference manual included in the distribution. Advanced API routine glp_free_env was added. It may be used by the application program to free all resources allocated by GLPK routines. The following three new command-line options were added to the solver glpsol: - --mipgap tol set relative MIP gap tolerance - -r filename read solution from filename - -w filename write solution to filename A minor bug was fixed for non-GNU platforms which do not support the standard function vsnprintf.
