Because then there is no need to write one's own `add_edges` etc. Graph does not have colouring methods for now, but pull-requests adding them (ideally with tests) are always welcome.	[reply] [d/l]

> but pull-requests adding them (ideally with tests) are always welcome. Graph coloring is a vast field, IMHO this would need to be addressed in an extra module. I was lucky to find a satisfying optimal solution, but only for the edge coloring of complete graphs (like requested by the OP) This edge-case (sic ;) can hardly be included in your very general module. And there is no easy generalization, according to WP is the general case of an optimal coloring known to be NP-hard.
