Figure 1. An illustration of the basic model in d = 2-dimensional space.

Figure 1

(a) The filled disks represent existing nodes, the red disk represents a newly added node that will survive. The dark lines represent existing links, and the dashed lines represent the newly added links. The shaded areas represent the interaction regions of existing nodes. (b) A simulation of the basic model after Inline graphic steps and Inline graphic nodes. The shaded area represents Inline graphic in two-dimensional space. In all simulations Inline graphic .
