  abstract =     "Genetic programming (GP), is a very general and
                 efficient technique, often capable of outperforming
                 more specialised techniques on a variety of tasks. In
                 this paper, we suggest a straightforward novel
                 algorithm for post-processing of GP classification
                 trees. The algorithm iteratively, one node at a time,
                 searches for possible modifications that would result
                 in higher accuracy. More specifically, the algorithm
                 for each split evaluates every possible constant value
                 and chooses the best. With this design, the
                 post-processing algorithm can only increase training
                 accuracy, never decrease it. In this study, we apply
                 the suggested algorithm to GP trees, extracted from
                 neural network ensembles. Experimentation, using 22 UCI
                 datasets, shows that the post-processing results in
                 higher test set accuracies on a large majority of
                 datasets. As a matter of fact, for two setups of three
                 evaluated, the increase in accuracy is statistically
