  abstract =     "The most effective approaches for evolutionary
                 identifying dynamical processes depend on iterative
                 trial-error searches in a hierarchical fashion: a new
                 structure is proposed first; then, its set of
                 parameters is numerically determined, and the process
                 is repeated until a model accurate enough is

                 Canonical Genetic Programming has been used to automate
                 this search; but its output can be diffcult to
                 interpret. Because of this reason, the use of
                 hierarchical learning methods, that combine GP search
                 of structures with deterministic optimisation
                 algorithms, has been proposed. We will show in this
                 paper that the output of such methods can be further
                 improved with non hierarchical algorithms. In
                 particular, we will show that the use of GA-P improves
                 the interpretability of the models and does a better
                 model search than previous approaches.",
