Currently the preprocessor is not used in glp_interior, though it is designed to allow recovering interior-point solutions as well. For testing/debugging you can call npp_build_prob, apply glp_interior to the transformed problem, and then call npp_postprocess to recover the original solution. (As I said in my previous mail, it would be reasonable to allow the user to access the preprocessed problem object, which currently is not available on api level.) _______________________________________________ Help-glpk mailing list [email protected] http://lists.gnu.org/mailman/listinfo/help-glpk
