attracting_components

attracting_components(G)[source]

Generates a list of attracting components in G.

An attracting component in a directed graph G is a strongly connected component with the property that a random walker on the graph will never leave the component, once it enters the component.

The nodes in attracting components can also be thought of as recurrent nodes. If a random walker enters the attractor containing the node, then the node will be visited infinitely often.

Parameters:G (DiGraph, MultiDiGraph) – The graph to be analyzed.
Returns:attractors – A generator of sets of nodes, one for each attracting component of G.
Return type:generator of sets
Raises:NetworkXNotImplemented : – If the input graph is undirected.
