)  ![Plot of the mean first-passage times $\langle T\rangle$ for walks as a function of distance $r$ between starting and target site for HN0 (top) and HN0 (bottom). The data has been scaled according to Eq. (\[eq:condamin\] such that the data collapses asymptotically onto a line that only depends on the model but that is independent of system size $N$. This collapse is excellent for HN0, it is somewhat weaker for HN0. Although all system sizes lead to linear forms in $\ln(r)$, their slope apparently varies with $N$. This could be caused by logarithmic scaling corrections to the slope, or by the lack of asymptotic behavior at the available system sizes $N$. []{data-label="fig:mfpt"}](mfpt_HN0
