Examine the code for the NetLogo Ants model, described in the chapter. The wiggle procedure right now has the ant turn a random amount to the left and then back to the right a random amount. This approximates a random walk that is centered on moving straight ahead. If you changed the procedure so the walk was biased to the left or to the right, how would that change the results? What if the limits of how much the ant turned were changed? Make these modifications and observe the results.
