As you can see, there are several peaks around 2.749 in the solution land-
scape and the HZero algorithm is able to jump from one to another with ease.
And running the GEP-PO algorithm for 2,000,000 generations (also two
orders of magnitude longer than in the experiment summarized in the second
column of Table 8.4), the following solutions were designed:
