abstract = "Genetic programming (Koza 1992) is a method of
inducing behaviors represented as executable programs.
The generality of the approach has spawned a
proliferation of work in the evolution of executable
structures that is unmatched in the history of the
subject. This paper describes the standard approach to
genetic programming, as defined in Koza (1992), and
then presents the significant studies that preceded its
inception as well as the diversification of techniques
evolving executable structures that is currently
underway in the field.",
