Node and link output fluxes. Histogram of the registered outgoing fluxes at node level (left) and at link level (right), comparing the two strategies Random Diffusion (top) and Strength Proportional (bottom) with respect to the O-D strategy. The color accounts for the number of nodes (left) or links (right) in each bin of the histogram. The values of the Pearson correlation are 0.998 (RD) and 0.952 (SP) for node flux, and 0.979 (RD) and 0.304 (SP) for link flux. The network is the World ATN, and the measured normalized fluxes do not depend on the details of the epidemic process.
