  abstract =     "This paper describes how the evolutionary mechanisms
                 of variation and selection can be used to evolve
                 complex equations used by procedural models for
                 computer graphics and animation. An interactive process
                 between the user and the computer allows the user to
                 guide evolving equations by observing results and
                 providing aesthetic information at each step of the
                 process. The computer automatically generates random
                 mutations of equations and combinations between
                 equations to create new generations of results. This
                 repeated interaction between user and computer allows
                 the user to search hyperspaces of possible equations
                 without being required to design the equations by hand
                 or even understand them. Three examples of these
                 techniques have been implemented and are described:
                 procedurally generated pictures and textures,
                 three-dimensional shapes represented by parametric
                 equations, and two-dimensional dynamical systems
                 described by sets of differential equations. It is
                 proposed that these methods have potential as powerful
                 tools for exploring procedural models and achieving
                 flexible complexity with a minimum of user input and
                 knowledge of details.",

                 preferable to adjust the mutation frequencies such that
                 a decrease in complexity is slightly more probable than
                 an increase. This prevents the expressions drifting
                 towards large and slow forms without necessarily
                 improving the results.{"} [page 469]",
