abstract = "Self Modifying Cartesian Genetic Programming 2
(SMCGP2) is a general purpose, graph-based,
developmental form of Cartesian Genetic Programming.
Using a combination of computational functions and
special functions that can modify the phenotype at
runtime, it has been employed to find general solutions
to a number of computational problems. Here, we apply
the new SMCGP technique to find mathematical
relationships between well known mathematical constants
(i.e. pi, e, phi, omega etc) using a variety of
functions sets. Some of formulae obtained are
distinctly unusual and may be unknown in mathematics.",
