boundaries of the world and started “reverberating”. Since this artifact occurred the fastest in a density-driven model, $\alpha_k=(1,0,0,0)$, we empirically assessed $T$ in that case and applied it everywhere.

Different parameter settings generated very diverse structures. In particular, we observed striking similarities between the patterns obtained for binary values of $\alpha_k$’s in some “corners” of the hypercube (one or two measures $d_k$ with weight 1, the others 0), and the fundamental urban configurations that Le Corbusier had identified in his 1945 analysis of human settlements [@mangin2004ville] (Fig. \[fig\_corbu\]).

![Typical patterns obtained from our model, reproducing Le Corbusier’s analysis of “human settlements”. In his 1945 attempt to theorize urban planning, Le Corbusier analyzed the form of cities by hand and outlined three types of settlements: radial-concentric cities, linear cities along communication roads, and rural communities. We were able to reproduce this typology by setting the weights of the explicative variables of our model to corner values: *Top-right*: $(\alpha_k)=(1,0,0,0)$, i.e. density-based only. *Middle*: $(0,1,0,0)$, i.e. distance-to-road only. *Bottom*: $(0.2,0,1,0)$, i.e. network-distance combined with a little density. *Left*: source [@mangin2004ville].[]{data-label="fig_corbu"}](corbu){width="\columnwidth"}
