The correct line is the following: tree->best = lpx_get_obj_val(lp); because the best known MIP solution is optimal solution of LP relaxation (which lp points to) corresponding to a node of the b&b tree. _______________________________________________ Help-glpk mailing list Help-glpk@gnu.org http://lists.gnu.org/mailman/listinfo/help-glpk
