Hi folks, This is now ticket #10433
http://trac.sagemath.org/sage_trac/ticket/10433 I opted to move the method min_spanning_tree() from Graph to GenericGraph. The code for Kruskal's algorithm has been moved to the new module spanning_tree.pyx and GenericGraph.min_spanning_tree() now calls spanning_tree.kruskal() if the former wants to use Kruskal's algorithm. Other (minimum) spanning tree algorithms will follow from #10433. -- Regards Minh Van Nguyen -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
