Evolving L-systems to generate virtual creatures

Evolving Legged Locomotion of Virtual Creatures

Virtual reality (VR) systems require realistic simulation of arti cial worlds inhabited by virtual creatures. The complex behavior of these creatures has to be guided by intelligent control systems. The paper discusses experiments on combining an explicit planning method with evolutionary computation techniques for the creation of a control system for a six-legged virtual creature modeled in a ...

Evolving a Diversity of Creatures through Novelty Search and Local Competition

An ambitious challenge in artificial life is to craft an evolutionary process that discovers a wide diversity of welladapted virtual creatures within a single run. Unlike in nature, evolving creatures in virtual worlds tend to converge to a single morphology because selection therein greedily rewards the morphology that is easiest to exploit. However, novelty search, a technique that explicitly...

Evolving Physical Creatures

One of the prevailing characteristics of natural life is autonomy. The field of Artificial Life has so far addressed the notion of autonomy mostly in terms of power and behavior. In this paper we attempt to extend the notion of autonomy to include also design and fabrication: We claim that not only should artificial creatures be able to operate untethered and without external guidance, but they...

Evolving Legged Locomotion in Virtual Creatures

Evolving Amphibian Behavior in Complex Environment

In this study, we aim to evolving autonomous virtual creatures which have complex shapes in a complex environment. We implement a basic physics law and fluid influences with a virtual environment and evolve artificial creatures in plural environments (on the ground, in the water). Each model, which is evolved in a different environment, obtains an effective moving behavior in each environment (...
