Please see an updated version of glpk here: http://sourceforge.net/projects/noumenon/files/tmp/ (Note that this is *not* an official release.)
In this release: 1. See http://lists.gnu.org/archive/html/help-glpk/2017-06/msg00032.html 2. A "smart" LP perturbation was implemented in the primal simplex solver. Now LP is perturbed only if it is necessary, and by default perturbation is not activated. 3. The sum of primal infeasibilites that appears in the terminal output of the primal simplex solver (as "inf = ...") now corresponds to the original bounds of variables. This allows to see how much perturbed LP solution violates the original bounds. 4. The Posix version of glp_time (see glpk/src/env/time.c) was changed to resolve time_t issue on msys2. Thanks to Rob Schroeder <[email protected]> for bug report.
