Community detection algorithm based on interacting fluids


The algorithm detects communities based on the simple idea of several fluids interacting in a non-homogeneous environment (the graph topology), expanding and contracting based on their interaction and density.


cluster_fluid_communities(graph, no.of.communities)



The input graph. The graph must be simple and connected. Empty graphs are not supported as well as single vertex graphs. Edge directions are ignored. Weights are not considered.


The number of communities to be found. Must be greater than 0 and fewer than number of vertices in the graph.


cluster_fluid_communities returns a communities object, please see the communities manual page for details.
