Liu, Jian-Guo Zhou, Tao Guo, Qiang Wang, Bing-Hong 2009 In this paper, we numerically investigate the structural characteristics that affect the synchronizability of coupled identical oscillators on scale-free networks. By using the edge-exchange method, we can change the network structure with degree sequence fixed. An optimal algorithm, namely Tabu Search, is applied, respectively, to enhance and weaken the synchronizability. The numerical results indicate that the synchronizability is most sensitive to the maximal betweenness. By tracking the optimization process, most previous works suggest that the synchonizability can be enhanced by reducing assortative coefficient and clustering coefficient; however, interestingly, our numerical simulations show that the depression of synchronizability also corresponds to the reduction process of those two coefficients. application/pdf https://folia.unifr.ch/global/documents/301081 https://folia.unifr.ch/documents/301081/files/zhou_ses.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.1142/S0129183108012960 info:eu-repo/semantics/openAccess License undefined International Journal of Modern Physics C. - 2008, vol. 19, no. 9, p. 1359 - 1366 info:eu-repo/classification/udc/53 Structural effects on synchronizability of scale-free networks http://purl.org/coar/resource_type/c_6501
