我们提出了一个有效的算法来生成具有给定序列的期望度的随机图。现有的算法运行时间为O(N2),其中N是节点数。我们证明了我们的算法运行在O(N +M)的预期时间,其中M是预期的边缘数。如果期望度是从有限均值分布中选择的,则当N → ∞时,这是O(N)。
We present an efficient algorithm to generate random graphs with a given sequence of expected degrees. Existing algorithms run in O(N2) time where N is the number of nodes. We prove that our algorithm runs in O(N +M) expected time where M is the expected number of edges. If the expected degrees are chosen from a distribution with finite mean, this is O(N) as N → ∞.
