Generates the attracting components in
An attracting component in a directed graph
Gis 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.
