  abstract =     "The concept of bloat --- the increase of program size
                 without a corresponding increase in fitness ---
                 presents a significant drawback to the application of
                 genetic programming. One approach to controlling bloat,
                 dubbed spatial structure with elitism (SS+E), uses a
                 combination of spatial population structure and local
                 elitist replacement to implicitly constrain unwarranted
                 program growth. However, the default implementation of
                 SS+E uses a replacement scheme that prevents the
                 introduction of smaller programs in the presence of
                 equal fitness. This paper introduces a modified SS+E
                 approach in which replacement is done under a
                 lexicographic parsimony scheme. The proposed model,
                 spatial structure with lexicographic parsimonious
                 elitism (SS+LPE), exhibits an improvement in bloat
                 reduction and, in some cases, more effectively searches
                 for fitter solutions.",
