  abstract =     "Hierarchical genetic programming (HGP) approaches rely
                 on the discovery, modification, and use of new
                 functions to accelerate evolution. This paper provides
                 a qualitative explanation of the improved behavior of
                 HGP, based on an analysis of the evolution process from
                 the dual perspective of diversity and causality. From a
                 static point of view, the use of an HGP approach
                 enables the manipulation of a population of higher
                 diversity programs. Higher diversity increases the
                 exploratory ability of the genetic search process, as
                 demonstrated by theoretical and experimental fitness
                 distributions and expanded structural complexity of
                 individuals. From a dynamic point of view, an analysis
                 of the causality of the crossover operator suggests
                 that HGP discovers and exploits useful structures in a
                 bottom-up, hierarchical manner. Diversity and causality
                 are complementary, affecting exploration and
                 exploitation in genetic search. Unlike other machine
                 learning techniques that need extra machinery to
                 control the tradeoff between them, HGP automatically
                 trades off exploration and exploitation.",
