Synthetic data produced through the proposed mechanism. (A) Growth of the number of distinct visited sites as a function of the number of RWs performed on a Watts–Strogatz network (see SI) of size 5 × 104 nodes and average degree 8, rewiring probability P = 0.1. Each RW has a random length l taken from a distribution P(l) ≈ l−3. The dotted line corresponds to a linear growth law, whereas the continuous line is a power-law growth with exponent 0.7. (Inset) Frequency-rank plot. The dashed and dotted line have slope −1.3 and −1.5, respectively. (B and C) Properties of the synthetic cooccurrence network obtained for nRW = 5 × 104, to be compared with the empirical data of Fig. 1.
