Dear colleagues,


For those of you who are interested in clustering (community detection)
algorithms, we would like to bring to your attention a new algorithm that we
have developed. The algorithm, referred to as a smart local moving
algorithm, can be used to perform clustering in very large networks, with
many millions of nodes and edges. The algorithm outperforms the well-known
'Louvain algorithm'. The algorithm can be applied in small and medium-sized
networks as well.


An open-source computer program implementing the new algorithm is available


A paper documenting the algorithm can be found at


Best regards,


Nees Jan van Eck
