The experimental simulations

Figure 7 illustrates the body usage statistic taken over the experimental population. The introduction of the predators had a clear effect on this statistic. Where the control group evolved smoothly to use their body less, the experimental group's body usage increased chaotically. This may be because the agents needed to be more efficient, and thus use more of their body. An emotional interpretation of the increased body use is that it is a result of hastened, less accurate decision making, causing jumps to less useful states.
