I'm learning to use minimize_nested_blockmodel_dl. I tried a 4 vertex graph that should result in two groups at the first level, but only one group is found. The code is below. I'm using v 2.35. Thanks, Stephan g = Graph() v0 = g.add_vertex() v1 = g.add_vertex() v2 = g.add_vertex() v3 = g.add_vertex() e01 = g.add_edge(v0, v1) e10 = g.add_edge(v1, v0) e23 = g.add_edge(v2, v3) e32 = g.add_edge(v3, v2) e03 = g.add_edge(v0, v3) edge_weights = g.new_edge_property('int') edge_weights[e01] = 5 edge_weights[e10] = 5 edge_weights[e23] = 5 edge_weights[e32] = 5 edge_weights[e03] = 1 state = minimize_nested_blockmodel_dl(g, overlap=False, state_args=dict(recs=[edge_weights], rec_types=['discrete-geometric']) ) print('Should be 2, but is ',state.levels[0].B) -- Sent from: https://nabble.skewed.de/
