Lpx_intopt does not support the callback, because it solves the problem instance transformed by the mip preprocessor. Even if lpx_intopt would allow that, it would be impossible to determine components of the original instance. Eventually glp_intopt will be provided with some generic cut generators (which currently I am working on) and, thus, will supersede lpx_intopt. _______________________________________________ Help-glpk mailing list [email protected] http://lists.gnu.org/mailman/listinfo/help-glpk
