Before call to lpx_simplex. > Do I have to call lpx_unscale_prob after calling lpx_simplex > to retrieve the solution and/or adding/removing rows to the problem ? It is not necessary. The scaling is performed internally and affects only the simplex solver; it is transparent to the user in the sense that all input data as well as resulting data provided by api routines are unscaled. _______________________________________________ Bug-glpk mailing list [email protected] http://lists.gnu.org/mailman/listinfo/bug-glpk
