Figure 3. Predators are choosier and take more steps when the per-step cost of dispersal is low.

Here we illustrate results obtained when the predators evolve a stopping rule that is sensitive to the ratio of prey per predator. The mean number of steps taken by predators is shown for a range of prey r and per-step mortality c_step in A. In B, C and D, we show the mean stopping rules that evolve for c_step = 0.02, 0.04 and 0.10, respectively.
