Coding Example of Ecosystem Based Solution

((* x (* x (+ y x)))) ((* y (+ (* y (+ (* y y) y)) y)))
((* (+ (* (+ (* y y) y) y) y) y)) ((* (+ y x) (* x x)))

Example of evolved ecosystem based solution for the longest evolutionary target used: f(x, y) = y4 + x3 + y3 + y * x2 + y2. These predator-scavenger combinations can feed perfectly on all possible prey in the model universe.
