is_multigraphical
(sequence)[source]¶ Returns True if some multigraph can realize the sequence.
Parameters: deg_sequence (list) – A list of integers Returns: valid – True if deg_sequence is a multigraphic degree sequence and False if not. Return type: bool Notes
The worst-case run time is \(O(n)\) where \(n\) is the length of the sequence.
