GLPK 4.52 Release Information
*****************************
Release date: July 18, 2013
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 C89 and
organized as a callable library.
In this release:
The clique cut generator was essentially reimplemented, and now
it is able to process very large and/or dense conflict graphs.
A simple rounding heuristic was added to the MIP optimizer.
Some bugs were fixed in the proximity search heuristic routine.
Thanks to Giorgio Sartor <0giok...@gmail.com>.
New command-line option '--proxy [nnn]' was added to glpsol to
enable using the proximity search heuristic.
A bug (incorrect processing of LI column indicator) was fixed
in the mps format reading routine. Thanks to Charles Brixko for
bug report.
