Abstract

A new approach for numerical-constant generation in Grammatical Evolution is presented. Experiments comparing our method with the three most popular methods for constant creation are performed. By varying the number of bits to represent a constant, we can increase our method's precision to the desired level of accuracy, overcoming by a large margin the other approaches.
