GLPK 2.4 -- Release Information

Release date: May 10, 2001

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.

Now GLPK includes an implementation of the GLPK/L modeling language,
which is intended for writing mathematical programming models. The name
GLPK/L is derived from GNU Linear Programming Kit Language.

A brief description of the GLPK/L language is given in the document
"GLPK/L Modeling Language: A Brief Description", which is included into
the distribution in plain text format (see the file 'language.txt' in
the subdirectory 'doc').

The language processor (which is a program that analyzes models written
in GLPK/L and translates them to internal data structures) is available
as the GLPK API routine.

The stand-alone solver GLPSOL now is able: a) to read model descriptions
written in the GLPK/L language; b) to solve pure LP problems using the
interior point method (therefore the program GLPIPM was removed from the

Please note that the current version of GLPK is *tentative*.
