Ni! Hi Alvaro, this is explained in the documentation for the graph_tool.generation.random_graph <https://graph-tool.skewed.de/static/doc/generation.html#graph_tool.generation.random_graph> function concerning the `deg_sampler`:
Optionally, you can also pass a function which receives one or two arguments. If block_membership is None, the single argument passed will be the index of the vertex which will receive the degree. If block_membership is not None, the first value passed will be the vertex index, and the second will be the block value of the vertex.

Hi,
I'm using graph-tool to try to generate random graphs with a sequence of degrees. For example, in a 3-node graph, I generated a random graph with all nodes with input degrees 1 and output degrees 1.
My code:
import graph_tool.all as gt>>> def deg_sampler():... return 1,1... >>> g = gt.random_graph(3,deg_sampler,parallel_edges=True, self_loops=False)>>> gt.graph_draw(g)
Can I generate a random graph defining the input and output degrees of each node? For example, tree nodes with respectively the input degrees (1, 2, 0) and output degrees (1, 0, 2).
Thanks,
Alvaro _______________________________________________ graph-tool mailing list graph-tool@skewed.de https://lists.skewed.de/mailman/listinfo/graph-tool
