John R. Koza, Martin A. Keane and Matthew J. Streeter, ``Evolving Inventions'', Scientific American, vol. 288, no. 2, Feb. 2003] mimic biological processes of evolution ; they can be used to find solutions in domains where:
Example: An animal might have variables color, percent-body-fat, length-of-legs.
It would be possible to use search on the discrete variables and hill-climbing on the continuous variables, but often the search space is too large.
