glpk 4.3

GLPK 4.3 -- Release Information

Release date: Dec 12, 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 4.3:

  • the bug, due to which the standard math library is not linked on building the package on some platforms, was fixed.
  • several new built-in functions were added to the MathProg language (round, trunc, Irand224, Uniform01, Uniform, Normal01, Normal).
  • the new api routine lpx_get_ray_info was added. It is intended to determine which (non-basic) variable causes primal unboundness.
  • some modules were corrected to avoid compilation errors on building the package on Mac OS X.
  • some new material was added to the GLPK documentation.

For more details please see ChangeLog.

mcron 1.0.0


I am pleased to annouce the release of GNU mcron 1.0.0. This is the first release as an a official GNU package, and follows four earlier pre-releases.

The GNU package mcron (Mellor's cron) is a 100% compatible replacement for Vixie cron. It is written in pure Guile, and allows configuration files to be written in scheme (as well as Vixie's original format) for infinite flexibility in specifying when jobs should be run.

While Savannah is reeling from convulsions, the package is being temporarily distributed from http://www.rdmp.org/mcron (web site) and ftp://ftp.rdmp.org (downloads). Mailing lists are currently being set up: bugs-mcron@gnu.org, help-mcron@gnu.org and info-mcron@gnu.org.
