  abstract =     "Biological organisms employ various mechanisms to cope
                 with the dynamic environments they live in. One recent
                 research reported that depending on the rates of
                 environmental variation, populations evolve toward
                 genotypes in different regions of the neutral networks
                 to adapt to the changes. Inspired by that work, we used
                 a genetic programming system to study the evolution of
                 computer programs under environmental variation.
                 Similar to biological evolution, the genetic
                 programming populations exploit neutrality to cope with
                 environmental fluctuations and evolve evolvability. We
                 hope this work sheds new light on the design of
                 open-ended evolutionary systems which are able to
                 provide consistent evolvability under variable
                 conditions.",

                 selected as non-solution. I.e. always-on is no worse
                 than anything else when selecting for even-4-parity.
