WLC Algorithm. Choosing the correct number of clusters. The ratio R (Eq. 5) of the mean child to parent infra-cluster affinities versus the number of clusters for B. subtilis generated by our WLC algorithm. As weakest links are severed, the number of clusters increases from 29 to 732. Note the stabilization at and around 350 clusters, the optimal cluster number.
