Comment on: 'Universal Behavior of Load Distribution in Scale-free Networks' | Marc Barthelemy
; | Date: |
14 Apr 2003 | Journal: | Phys. Rev. Lett. 91, 189803 (2003) | Subject: | Disordered Systems and Neural Networks; Statistical Mechanics | cond-mat.dis-nn cond-mat.stat-mech | Abstract: | In a previous Letter (cond-mat/0106565), Goh et al have presented a numerical study of the load--or betweenness centrality--distribution in a scale-free network whose degree distribution follows a power law with a tunable exponent $gamma$. They showed that the load $ell$ is distributed according to a power-law with exponent $delta$. The authors claimed that $delta$ is universal, ie. independent of the exponent $gamma$. In this comment, we use two different ways of checking numerically this universality and we show that it does not hold. | Source: | arXiv, cond-mat/0304314 | Other source: | [GID 1016480] pmid14611327 | Services: | Forum | Review | PDF | Favorites |
