k_crust¶
- k_crust(G, k=None, core_number=None)[source]¶
Return the k-crust of G.
The k-crust is the graph G with the k-core removed.
Parameters : G : NetworkX graph
A graph or directed graph.
k : int, optional
The order of the shell. If not specified return the main crust.
core_number : dictionary, optional
Precomputed core numbers for the graph G.
Returns : G : NetworkX graph
The k-crust subgraph
Raises : NetworkXError
The k-crust is not defined for graphs with self loops or parallel edges.

Notes
This definition of k-crust is different than the definition in [R228]. The k-crust in [R228] is equivalent to the k+1 crust of this algorithm.
Not implemented for graphs with parallel edges or self loops.
For directed graphs the node degree is defined to be the in-degree + out-degree.
Graph, node, and edge attributes are copied to the subgraph.
