GLPK 4.6 -- Release Information

Release date: Aug 04, 2004

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 4.6:

Three new statements were implemented in the GNU MathProg language: solve, printf, and for. Their detailed description can be found in the GLPK documentation included in the distribution. (See also a sample model, examples/queens.mod, which illustrates using these statements.)

Two new API routines were added to the package: lpx_read_prob and lpx_write_prob. They allow reading/writing problem data in GNU LP text format.

Three new command-line options were implemented in the LP/MIP solver glpsol: --glp (to read problem data in GNU LP format), --wglp (to write problem data in GNU LP format), and --name (to change problem name). Now glpsol also supports processing models where the new statements (mentioned above) are used.

A new version of GLPKMEX, a Matlab MEX interface to GLPK, was included. For more details see contrib/glpkmex/ChangeLog.

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 from some mirror ftp sites; see <http://www.gnu.org/order/ftp.html>.

MD5 check-sum is the following:
