glpk-help, I am attaching 3 versions of the same model that differe in their limits on two rows. KnockoutRow and KnockoutRow_up
All versions of the model display the error: spx_simplex: numerical instability (primal simplex, phase I) However the version ec_kn10_kca_mps.txt loops infinitely Also all column ending in _kcol are intended to be integer (actualy binary as their lower limit = 0 and upper limit = 1)). I am attaching the output as well. I have tried scaling my objective function (which has a coeffecent of 1) by small numbers and scalling my limits as well but neither approach has helped remove the instabilities. Graham Rockwell ec_kn0_kc0_mps.txt created error1.txt ec_kn10_kca_mps.txt created error2.txt (I removed attachments, since they are very large. - Andrew Makhorin.) _______________________________________________ Help-glpk mailing list [email protected] http://lists.gnu.org/mailman/listinfo/help-glpk
