- directed_havel_hakimi_graph(in_deg_sequence, out_deg_sequence, create_using=None)#
Returns a directed graph with the given degree sequences.
- in_deg_sequencelist of integers
Each list entry corresponds to the in-degree of a node.
- out_deg_sequencelist of integers
Each list entry corresponds to the out-degree of a node.
- create_usingNetworkX graph constructor, optional (default DiGraph)
Graph type to create. If graph instance, then cleared before populated.
A graph with the specified degree sequences. Nodes are labeled starting at 0 with an index corresponding to the position in deg_sequence
If the degree sequences are not digraphical.
