  abstract =     "Gene Expression Programming (GEP) is a new
                 evolutionary algorithm that incorporates both the idea
                 of simple, linear chromosomes of fixed length used in
                 Genetic Algorithms (GAs) and the structure of different
                 sizes and shapes used in Genetic Programming (GP). As
                 with other genetic programming algorithms, GEP has
                 difficulty finding appropriate numeric constants for
                 terminal nodes in the expression trees. In this paper,
                 we describe a new approach of constant generation using
                 Differential Evolution (DE), which is a simple
                 real-valued GA that has proven to be robust and
                 efficient on parameter optimisation problems. Our
                 experimental results on two symbolic regression
                 problems show that the approach significantly improves
                 the performance of the GEP algorithm. The proposed
                 approach can be easily extended to other Genetic
                 Programming variants.",
