- random_powerlaw_tree_sequence(n, gamma=3, seed=None, tries=100)¶
Return a degree sequence for a tree with a powerlaw distribution.
n : int,
The number of nodes
gamma : float
Exponent of the power-law
seed : int, optional
Seed for random number generator (default=None).
tries : int
Number of attempts to adjust sequence to make a tree
A trial powerlaw degree sequence is chosen and then elements are swapped with new elements from a powerlaw distribution until the sequence makes a tree (#edges=#nodes-1).
