Query: Scale-Free Networks with the Same Degree Distribution: Different
  Structural Properties   We have analysed some structural properties of scale-free networks with the
same degree distribution. Departing from a degree distribution obtained from
the Barab\'asi-Albert (BA) algorithm, networks were generated using four
additional different algorithms a (Molloy-Reed, Kalisky, and two new models
named A and B) besides the BA algorithm itself. For each network, we have
calculated the following structural measures: average degree of the nearest
neighbours, central point dominance, clustering coefficient, the Pearson
correlation coefficient, and global efficiency. We found that different
networks with the same degree distribution may have distinct structural
properties. In particular, model B generates decentralized networks with a
larger number of components, a smaller giant component size, and a low global
efficiency when compared to the other algorithms, especially compared to the
centralized BA networks that have all vertices in a single component, with a
medium to high global efficiency. The other three models generate networks with
intermediate characteristics between B and BA models. A consequence of this
finding is that the dynamics of different phenomena on these networks may
differ considerably.
