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