O_O;;;; What about giving them a different name then ? If Bipartite graphs are "not just Bipartite graphs" ? :-p > The BipartiteGraph object should have additional structure, > namely the vertex partition.

I think it would be nice to make it mandatory, so that there is no way to build a BipartiteGraph without *knowing* that the actual bipartition is one of the graph's constants. Then, of course, we would have to change the is_isomorphic function (it does not take the bipartition into account). Then we would lose the sparse6_string export -- it would not represent the graph's structure anymore. Ahahahah. The nice thing is that when something just isn't meant to be you see it cracking everywhere :-p Nathann -- -- 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
