Evolving Adaptation in Virtual Creatures

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 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 (...

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 ...

Neuro - Morpho Evolution : What will happen if our body is not symmetric ?

In this study, we evolve both the controller and morphology of artificially embodied legged creatures. This is achieved by relaxing certain morphological constraints previously imposed on the artificial creature where the focus had only been on the optimization of its artificial neural network (ANN) controller. The first objective is to explore the legged locomotion behaviors that can be achiev...
