Abstract
When generating a random graph, if more structure is desired than is given in the popular Erd\H{o}s Renyi model, one method is to generate a degree sequence first then create a graph with this degree sequence. Blitzstein and Diaconis (among others) developed a sequential algorithm to create a random graph from a degree sequence. This algorithm is assured to always terminate in a graph with the degree sequence; unfortunately, it is slow. This work focuses on the subroutine of the previous algorithm which determines the candidate edges, improving the runtime of the overall algorithm from O(mn2) to O(mn).Citation
