  abstract =     "Operator equalisation was recently proposed as a new
                 bloat control technique for genetic programming. By
                 controlling the distribution of program lengths inside
                 the population, it can bias the search towards smaller
                 or larger programs. In this paper we propose a new
                 implementation of operator equalisation and compare it
                 to a previous version, using a hard real-world
                 regression problem where bloat and overfitting are
                 major issues. The results show that both
                 implementations of operator equalisation are completely
                 bloat-free, producing smaller individuals than standard
                 genetic programming, without compromising the
                 generalization ability. We also show that the new
                 implementation of operator equalisation is more
                 efficient and exhibits a more predictable and reliable
                 behavior than the previous version. We advance some
                 arguable ideas regarding the relationship between bloat
                 and overfitting, and support them with our results.",
