  abstract =     "Generalization is a very important issue in Machine
                 Learning. In this paper, we present a new idea for
                 improving Genetic Programming generalization ability.
                 The idea is based on a dynamic two-layered selection
                 algorithm and it is tested on a real-life drug
                 discovery regression application. The algorithm begins
                 using root mean squared error as fitness and the usual
                 tournament selection. A list of individuals called
                 ``repulsors'' is also kept in memory and initialized as
                 empty. As an individual is found to overfit the
                 training set, it is inserted into the list of
                 repulsors. When the list of repulsors is not empty,
                 selection becomes a two-layer algorithm: individuals
                 participating to the tournament are not randomly chosen
                 from the population but are themselves selected, using
                 the average dissimilarity to the repulsors as a
                 criterion to be maximized. Two kinds of
                 similarity/dissimilarity measures are tested for this
                 aim: the well known structural (or edit) distance and
                 the recently defined subtree crossover based similarity
                 measure. Although simple, this idea seems to improve
                 Genetic Programming generalization ability and the
                 presented experimental results show that Genetic
                 Programming generalizes better when subtree crossover
                 based similarity measure is used, at least for the test
                 problems studied in this paper.",
