Fig. 2.

Variance of random walkers in continuous time with Mittag-Leffler distributed waiting times with varying values of μ, τ₀ = 1, α/2 = 1/2, t_end = 10³, and N = 10⁴. The blue dashed line shows $\text{Var}\left[{\overline{X}}_{\mu }(t)\right]\propto t^2$. The red dotted line shows $\text{Var}\left[{\overline{X}}_{\mu }(t)\right]\propto t$.
