Figure 3. Spreading time over percentage of edges removed by edge betweenness centrality for four different rewired versions of the original airline network: fully randomized, randomized only within communities, preserving only the original degree distribution and preserving the degree distribution plus original communities. A spreading time ratio of 2 would mean spreading took twice the number of time steps compared to the intact network. Due to the greater spreading times observed for networks where links were randomized within communities (top left) a larger scale y-axis scale was used.
