Re: [igraph] signal diffusion and weighted networks

[Hermann Norpois]

Yes. I was not precise. I am not sure if diffusion is the correct term ... Imagine the edges are tubes and the weights are diameters and then you inject blue ink in vertex i the blue color will distribute according to the weighted edges (please forget the diluation effect). I wish to know what are the first 30 vertices that are affected. Thanks

Please provide a more detailed definition of what you mean by "diffusion" --
the neighborhoods of vertices do not change if the edges are weighted so I'm
pretty sure that you mean something else here and not just the neighboring
vertices.
