**Figure 3:** (a) Exceedence probability (noted PE) of the tree-density differences
against tree-density differences (Δd) presented in a loglog plot. 5000 dots were
used in the original plot, while circles correspond to the fit with 50 regular bins.
The same plot for the random landscape of figure 1b is shown for comparison,
while its shape is highlighted with a linear fit (line, inset). (b) Hamiltonian
function (noted H) extracted from the exceedence probability of the reference
landscape. Here, dots correspond to open circles in figure 2. The slope γ of this
loglog plot is highlighted with a mean-square linear fit. |
