Migration in networks with stiffness gradient in x-direction and a line density of $4.9\times {10}^{-2}$ μm^-2. We studied contraction rates of a $\dot{c}=0.05$μm/s. b $\dot{c}=0.1$ μm/s. c $\dot{c}=0.15$ μm/s with $N=5$ realizations (different colors), respectively. The mean migration rate (black) increases with $\dot{c}$
