This package implements the louvain algorithm inC++and exposes it topython. It relies on(python-)igraphfor it to function. Besides the relative flexibility of the implementation, it also scales well, and can be run on graphs of millions of nodes (as long as they can fit in memory). The ...
4 = Leiden algorithm). Leiden requires the leidenalg python. 以下简称 [算法1-4]。 默认值是1,精力有限,我们也只看第一个算法,其他略过。 先看该函数的文档: Identify clusters of cells by a shared nearest neighbor (SNN) modularity optimization based clustering algorithm.Firstcalculate k-nearest neigh...

Louvain的分布式实现在[10]中有给到,非分布式对应着python-igraph的multilevel方法。python-igraph这个library中,fast_greedy对应的是[6],属于很早期的工作。infomap很慢,不知道时间复杂度是多少。label_propagation是[2]的工作,速度比louvain稍慢,但是也有resolution的问题 [3],并且是potts模型的一个特例。leading_eig...
