GLPK 4.62 Release Information
*****************************
Release date: June 14, 2017
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 bound perturbation technique was included in the primal
simplex solver to improve numerical stability and avoid cycling.
Currently this feature is enabled by default.
A range bug was fixed in the MPS reading routine. Thanks to
Chris Matrakidis <[email protected]> for bug report and patch.
Changes were made to provide 64-bit portability of the Minisat
solver. Thanks to Chris Matrakidis <[email protected]> for
patch.
Calls to non-thread-safe functions gmtime, strerror, and strtok
were replaced by calls to corresponding thread-safe equivalents
(gmtime_r, strerror_r, and strtok_r for GNU/Linux).
