Let us closely examine the connected_components ( G ), â¦ You can create a list of items in the generator using the Python list function. If you only want the largest connected component, itâs more efficient to use max instead of sort. A directed graph is weakly connected (or just connected [5]) if the undirected underlying graph obtained by replacing all directed edges of the graph with undirected edges is a connected graph.

Components » is_connected Edit on GitHub is_connected is_connected (G) [source] Return True if the graph is connected, false otherwise. A directed graph is weakly connected if, and only if, the graph is connected when the direction of the edge between nodes is ignored. You can use the alternative described in the deprecation notice.
