Currently such a feature is not supported. > Is possible to modify the B C api #39;s to obtain that list? In principle, yes. You can trace each new node of the tree in the the callback routine specifying it in the parameter list passed to glp_intopt. For more details please see the glpk reference manual included in the distribution. Another way is to patch the glpk source code (see the routine ios_driver in file src/glpios03.c). See also the BAK package developed by Brady Hunsaker, which allows visualizing the search tree for three mip solvers including glpk: http://www.rosemaryroad.org/brady/software/index.html _______________________________________________ Help-glpk mailing list [email protected] http://lists.gnu.org/mailman/listinfo/help-glpk
