  abstract =     "The dominant paradigm for 3-D character animation
                 requires an animator to specify the values for all
                 degrees of freedom of an articulated figure at key
                 frames. Specifying motion that is physically believable
                 and biologically plausible is a tedious practice
                 requiring great skill. We use evolutionary techniques
                 (specifically Genetic Programming) as a means of
                 controller synthesis for character animation.
                 Controllers which drive a dynamic simulation of the
                 character are evolved using the goals of the animation
                 as an objective function, resulting in physically
                 plausible motion. We discuss the development of
                 objective functions used to guide the controller
                 evolution, making reusable skill controllers, and
                 comparisons of the convergence rates for different
                 parameters of the evolutionary runs.",
