GLPK 3.2.3 -- Release Information

Release date: Nov 11, 2002

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.

A new implementation of the api routine lpx_integer which now is based
on the b&b driver (which is based on the implicit enumeration suit) was
included in the package. This new implementation has exactly the same
functionality as the old version, so all changes are transparent to the
api user.

Four new api routines were included in the package:
lpx_check_kkt  check Karush-Kuhn-Tucker optmality conditions;
lpx_read_bas   read predefined basis in MPS format;
lpx_write_bas  write current basis in MPS format;
lpx_write_lpt  write problem data in CPLEX LP format.

Three new command-line options were introduced to the solver glpsol:
--plain (use plain names), --orig (use original names), and --wrlpt
(write problem data in CPLEX LP format).

Also other minor improvements were made (see the file 'ChangeLog').

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