The lamb’s expected lifetime 〈T〉 vs. (a) the number of lions n and (b) the degree of the lamb’s site k_lamb. The underlying network is generated by the Price model. The network parameters are the same for panels (a) and (b), which are N = 1000, 〈k〉 = 10, and γ = 2.5. The random walk parameter α equals 0 for both panels. In panel (b), the number of lions n is 10. The details about the sites’ selection for the lamb and lions are illustrated in the text. Each data point is the average of 10⁴ independent runs.
