# is_multigraphical¶

is_multigraphical(sequence)[source]

Returns True if some multigraph can realize the sequence.

Parameters: deg_sequence (list) – A list of integers valid – True if deg_sequence is a multigraphic degree sequence and False if not. bool

Notes

The worst-case run time is O(n) where n is the length of the sequence.
