Robbie, The "strange" behavior of the simplex solver is caused by small objective coefficients; they are of the order 1e-9, i.e. even less than the reduced cost tolerance (which is 1e-8 by default). In the current implementation the objective row is not scaled, so the solver just "think" that reduced costs are small enough to terminate the search.
Scaling the objective row by multiplying all objective coefficients, say, by 1e+9 resolves the problem. _______________________________________________ Help-glpk mailing list Help-glpk@gnu.org http://lists.gnu.org/mailman/listinfo/help-glpk
