Comment (by borassi):
Hellooooooo!
I have done it, but there is a problem: in order to obtain this result,
`generic_graph` should import `boost_graph`, which imports
`directed_graph`, which imports `generic_graph`, and I have cyclic
dependencies. I tried to put
{{{
import types
from sage.graphs.generic_graph import GenericGraph
GenericGraph.dominator_tree = types.MethodType(dominator_tree, None,
GenericGraph)
}}}
inside boost_graph, but it is not imported when Sage starts, so I have to
import boost_graph before running dominator_tree (and I don't like it).
Any suggestion?
Replying to [comment:16 dcoudert]:
> A good example is `GenericGraph.diameter =
types.MethodType(sage.graphs.distances_all_pairs.diameter, None,
GenericGraph)`.
> It has several arguments (e.g. `method='iFUB'`).
