Here, τ is the mean time between collisions.

This means that at time tb the random walk S is at the point 32 and at time tb + 25 it is at the point 51, but strictly in between the time tb until time tb + 25 the random walk S does not visit the points 32 or 51.

However the microscopic time scale in our examples is infinite, namely the mean trapping times or the mean dark and bright times diverge.
A Random Walk to a Non-Ergodic Equilibrium Concept
If the first moment of the waiting time distribution is finite, we have tx /t = nx /n, since the average time spent on x is nx times the mean waiting time.
A Random Walk to a Non-Ergodic Equilibrium Concept
One may find that there are similarities of the d-dimensional analog of the model of with our model, because clusters of size n will have “density” e−C n , and the mean time spent there is roughly eβn , so, thinking of clusters as “sites”, we indeed obtain a polinomial tail of mean time spent at a given site.
Random walk attracted by percolation clusters
We perform computer simulations for the mean first passage time, the average return time, the mean-square displacement, and the network coverage for unrestricted random walk.
Walks on Apollonian networks
For the mean value of the cavity decay time, given by τc,mm , we use the mean value of the distribution of the decay times.
