Dear all, I have a general question regarding LPs. A LP should have one solution and so a basis which has normal and dual information. Via changing the LP (Adding one variable for some inequalities, changing the objective function and changing the limits of the inequalities a little bit, you consider a second LP. The dual inequalities from the basis still have the property that the indicated solution is quite near the new optimal solution and also 0 is in the dual solution space of the second problem.
But the normal information from the basis is not applicable anymore. Is it possible to work with the old basis in general at LPs and specifically at glpk? Best regards Harald. _______________________________________________ Help-glpk mailing list Help-glpk@gnu.org http://lists.gnu.org/mailman/listinfo/help-glpk
