  abstract =     "Motion data is required for realistic animation of
                 physics-based animal models. This data is expensive to
                 acquire for a single animal and in herd situations, the
                 large variation in animal shape and consequent motion
                 increases this expense. We propose a method in which
                 data measured from a single horse can be used to
                 animate horses of different age, breed and
                 conformation. The construction and animation of a
                 physics-based horse is described. Details of an
                 application, which automatically generates horse models
                 of a user-specified age, are also presented. We compare
                 two approaches in which Grammatical Evolution is used
                 to optimise a generated model's motion parameters, to
                 produce realistic motion. In one approach, the constant
                 coefficients of a model's spring-damper based muscle
                 system are optimised prior to the gait optimisation. We
                 contrast this method with a parallel optimisation of
                 both spring-damper constants and gait. The sequential
                 approach was found to be the most successful for gait
