As stated in the documentation, like eweight, vweight denotes multiplicity. So a node v with vweight[v] == 2 counts as two nodes. These parameters are useful for working with summarized versions of the network, which are used by some algorithms in graph-tool. It is meant mostly for internal use, not as a means of introduction arbitrary weights to nodes and edges. > I believe that if the eweight between a pair of nodes is increased, then the > two nodes are more likely to end up in the same block (more or less). Would > the opposite be true if their vweight is increased? No, this interpretation is not correct. Increasing the edge or node multiplicity can have varied effects, it depends on the rest of the network. Best, Tiago -- Tiago de Paula Peixoto <[email protected]>
