Hi,

I am aware of a post asking for the same topic, but it was dated 2 years ago, but I wonder if there was any development on this front?

In the function "model.minimize_nested_blockmodel_dl" it is possible to specify B_min=G and B_max=G in order to get exactly G blocks for the whole clustering. I wonder if it is possible to specify separately the number of blocks on each side of the bi-partite network, say G1 for one side of the network and G2 for the other side? Even maybe by running 2 different estimations?

Unfortunately, this functionality has not been implemented yet.

I also noticed that Tzu-Chi Yen has an alternative code for this, but I wonder how comparable it is to graph-tool in terms of efficiency?

Code: https://github.com/junipertcy/bipartiteSBM <https://github.com/junipertcy/bipartiteSBM>Related doc:https://docs.netscied.tw/bipartiteSBM/usage/explore-consistency.html <https://docs.netscied.tw/bipartiteSBM/usage/explore-consistency.html>

As you can see for yourself, that implementation is in pure Python, whereas graph-tool is implemented in C++. Therefore it should be much slower than graph-tool. Best, Tiago -- Tiago de Paula Peixoto <tiago@skewed.de>
