k_crust¶

k_crust
(G, k=None, core_number=None)[source]¶ Return the kcrust of G.
The kcrust is the graph G with the kcore 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 – The kcrust subgraph
Return type: NetworkX graph
Raises: NetworkXError
– The kcrust is not defined for graphs with self loops or parallel edges.Notes
This definition of kcrust is different than the definition in [1]. The kcrust in [1] 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 indegree + outdegree.
Graph, node, and edge attributes are copied to the subgraph.
