  abstract =     "Parsimony pressure, the explicit penalization of
                 larger programs, has been increasingly used as a means
                 of controlling code growth in genetic programming.
                 However, in many cases parsimony pressure degrades the
                 performance of the genetic program. In this paper we
                 show that poor average results with parsimony pressure
                 are a result of {"}failed{"} populations that
                 overshadow the results of populations that incorporate
                 parsimony pressure successfully. Additionally, we show
                 that the effect of parsimony pressure can be measured
                 by calculating the relationship between program size
                 and performance within the population. This measure can
                 be used as a partial indicator of success or failure
                 for individual populations.",
