ZHANG, Jin-Fang; SHAO, Zhi-Gang y YANG, Lei. Efficiency dynamics on two coupled small-world networks. Braz. J. Phys. [online]. 2010, vol.40, n.4, pp. 419-422. ISSN 0103-9733. http://dx.doi.org/10.1590/S0103-97332010000400011.
We investigate the effect of clusters in complex networks on efficiency dynamics by studying a simple efficiency model in two coupled small-world networks. It is shown that the critical network randomness corresponding to transition from a stagnant phase to a growing one decreases to zero as the connection strength of clusters increases. It is also shown for fixed randomness that the state of clusters transits from a stagnant phase to a growing one as the connection strength of clusters increases. This work can be useful for understanding the critical transition appearing in many dynamic processes on the cluster networks.
