Figure 11.
(A) The Eden model on a two-dimensional lattice. Cells that are completely surrounded and cannot replicate are shown in yellow. The bright green cell illustrates the replication rules: it can replicate to a neighbouring empty lattice site (including the diagonal ones in this variant of the model) but not to an occupied one. (B) A snapshot of a simulation of the two-dimensional Eden model in which a cluster of cells (N = 65536) has grown from a single initial cell. (C) Simulation snapshot for a two-dimensional Eden model in a domain of width L = 250 that is semi-infinite in the vertical dimension, with periodic boundaries in the horizontal dimension.
