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 → ∞.
