  abstract =     "Genetic programming methods often suffer from `code
                 bloat,' in which evolving solution trees rapidly become
                 unmanageably large. To provide a measure of sensitivity
                 to tree size in a natural way, we introduce a simple
                 uniform subtree mutation (USM) operator that provides
                 an approximately constant probability of mutation per
                 tree node, rather than per tree. To help model
                 circumstances where tree size cannot be ignored, we
                 introduce a new notion of computational effort called
                 size effort. Initial empirical tests show that genetic
                 programming using only uniform subtree mutation reduces
                 evolved tree sizes dramatically, compared to crossover,
                 but does impact solution quality somewhat. In some
                 cases, however, using using a combination of USM and
                 crossover yielded both smaller trees and superior
                 performance, as measured both by size effort and
                 traditional metrics.",
