abstract = "The selection of program representation can have
strong impact on the performance of genetic
programming. Previous work has shown that a particular
program representation which supports structure
abstraction is very effective in solving the general
even parity problem. We investigate program structures
and analyse all perfect solutions in the search space
to provide explanation of why structure abstraction is
so effective with this problem. This work provides
guidelines for the application of structure abstraction
to other problems",
