GLPK 4.10 -- Release Information
================================

Release date: May 11, 2006

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:

Cutting planes of two new classes were implemented: mixed cover cuts and
clique cuts. On API level this feature can be enabled by setting control
parameter LPX_K_USECUTS passed to the routine lpx_intopt. In glpsol this
feature is available through the command-line options --cover and
- --clique. For more details see the reference manual.

Now the routines lpx_read_mps and lpx_read_freemps support LI bound
type. It is similar to LO, however, indicates the column as of integer
kind.

As usual some bugs were fixed.

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>.
