> What I #39;m doing wrong? You make *wrong* assumption that the subproblem reference number returned by glp_ios_curr/up/next/prev_node uniquely identifies the corresponding node of the search tree. The reference number assigned to a subproblem is valid only while its node exists in the tree. Once the subproblem has been fathomed, its node is removed from the tree, in which case the corresponding reference number is freed and can be assigned to any other new subproblem appearing in the tree. _______________________________________________ Help-glpk mailing list [email protected] http://lists.gnu.org/mailman/listinfo/help-glpk
