However, glpk is able to correctly process unbounded integer variables. The bug appear due to insufficient robustness of the mip preprocessor--there should be a check that an lower/upper bound of an integer variable increases/decreases too much. _______________________________________________ Bug-glpk mailing list Bug-glpk@gnu.org https://lists.gnu.org/mailman/listinfo/bug-glpk
