  abstract =     "Previous work on introns and code growth in genetic
                 programming is expanded on and tested experimentally.
                 Explicitly defined introns are introduced to tree-based
                 representations as an aid to measuring and evaluating
                 intron behavior. Although it is shown that introns do
                 create code growth, they are not its only cause.
                 Removing introns merely decreases the growth rate; it
                 does not eliminate it. By systematically negating
                 various forms of intron behavior, a deeper
                 understanding of the causes of code growth is obtained,
                 leading to the development of a system that keeps
                 unnecessary bloat to a minimum. Alternative selection
                 schemes and recombination operators are examined and
                 improvements demonstrated over the standard selection
                 methods in terms of both performance and parsimony.",
