Analysing co-evolution among artificial 3D creatures [PDF]

open access: yes, 2006
This paper is concerned with the analysis of coevolutionary dynamics among 3D artificial creatures, similar to those introduced by Sims (1). Coevolution is subject to complex dynamics which are notoriously difficult to analyse.
