It is difficult to determine if it is reasonable to continue the search or not, because in many cases numerical instability does not prevent the solver to complete the search. This, of course, should be considered as a defect of the glpk solver. It seems that you are using some old version of glpk. Try using the most recent version, which is 4.33. _______________________________________________ Help-glpk mailing list Help-glpk@gnu.org http://lists.gnu.org/mailman/listinfo/help-glpk
