Particle number within r = 30 pc from the cluster center as a function of time for all 15 runs of the ensemble en3000W6. One can see the non-Markovian process of star cluster dissolution. The mean final particle number and the standard deviation for a single run is shown as a (red) dot with vertical errorbars at t = 625 Myr. The future evolution of the mean particle number within r = 30 pc is shown in the inset. There the times when the cluster has reached 20, 10 and 5% of its initial particle number are shown as (red) dots.
