Figure 8. Neutrally fit invader $(r=1)$.

Simulated and fitted distributions of invader fixation times are shown for Birth-death dynamics on various networks. All distributions were normalized to have mean zero and unit variance. The curves indicate noncentral lognormals fitted via the method of moments. (a) Complete graph on $N=50$ nodes, for ${10}^6$ runs. (b) Star graph with $N=25$ spokes, for ${10}^6$ runs. (c) One-dimensional ring on $N=50$ nodes, for ${10}^6$ runs. (d) Two-dimensional lattice on $N=7\times 7$ nodes, for ${10}^6$ runs. (e) Three-dimensional lattice on $N=4^3$ nodes for ${10}^6$ runs. (f) Erdős-Rényi random graph on $N=25$ nodes with an edge probability of $\rho =0.5$.
