The following are 15 code examples for showing how to use networkx.strongly_connected_component_subgraphs().These examples are extracted from open source projects. At this stage single-node loops are ignored, # since nx.strongly_connected_components() returns components also # consisting of a single nodes without any self-looping edge. Last updated on Oct 26, 2015. The strongly connected components of an arbitrary directed graph form a partition into subgraphs that are themselves strongly connected. For undirected graphs only.
