Figure 7. Time needed to cover 50% of all nodes on three types of multiplex networks, as a function of the inter-layer weight D_X.

We compare the results obtained for the Lévy random walk (RWL) studied here with three other scenarios for the walks, as discussed in the text. The values of θ considered are 1, 5, 10, respectively. Each layer has 10³ nodes and all the simulations were averaged over 100 realizations.
