I remember there was a paper regarding scale-free networks. I believe it was discussed on HN a few months back: https://news.ycombinator.com/item?id=16144867 https://news.ycombinator.com/item?id=16144867 But I also (perhaps falsely) remember a discussion that seemed to challenge the small-world networks as well, so that may not be the discussion I was thinking of. I may not have engaged my brain at the time but I'd be surprised if it was small-world networks given the widely-reproduced evidence for the effect.
