Query: Increasing Behavioral Complexity for Evolved Virtual Creatures with the
  ESP Method   Since their introduction in 1994 (Sims), evolved virtual creatures (EVCs)
have employed the coevolution of morphology and control to produce high-impact
work in multiple fields, including graphics, evolutionary computation,
robotics, and artificial life. However, in contrast to fixed-morphology
creatures, there has been no clear increase in the behavioral complexity of
EVCs in those two decades. This paper describes a method for moving beyond this
limit, making use of high-level human input in the form of a syllabus of
intermediate learning tasks--along with mechanisms for preservation, reuse, and
combination of previously learned tasks. This method--named ESP for its three
components: encapsulation, syllabus, and pandemonium--is presented in two
complementary versions: Fast ESP, which constrains later morphological changes
to achieve linear growth in computation time as behavioral complexity is added,
and General ESP, which allows this restriction to be removed when sufficient
computational resources are available. Experiments demonstrate that the ESP
method allows evolved virtual creatures to reach new levels of behavioral
complexity in the co-evolution of morphology and control, approximately
doubling the previous state of the art.
