The Barabási – Albert paper “Emergence of Scaling in Random Networks” helped popularise the preferential-attachment model of graphs, and its relevance to a number of real-world graphs. There’s a small, somewhat trivial tweak to that model that can be made which never the less changes its characteristics slightly, with the result possibly being more relevant to the BGP AS graph. GNU Octave and Java implementations are given for the original BA-model and the tweak. The tweak can also potentially improve performance of vectorised implementations, such as Octave/Matlab.
