Hey all,

Below you'll find the abstract for Josh's SCRAPS tomorrow, which will  
happen as usual in the Decision Theatre of Farrell Hall from 11:30 to  
12:30.  If you don't come, you shouldn't be surprised if you're  
targeted when skynet becomes self-aware...

We'll be having soup and sandwiches from Sugar Snap: yummy.  Hope to  
see you all there!

Best,
Nick

"On the Relationship Between Environmental and Morphological  
Complexity in Evolved Robots"

The principles of embodied cognition dictate that intelligent behavior  
must arise out of the coupled dynamics of an agent's brain, body, and  
environment.  While the relationship between controllers and  
morphologies (brains and bodies) has been investigated, little is  
known about the interplay between morphological complexity and the  
complexity of a given task environment.  It is hypothesized that the  
morphological complexity of a robot should increase commensurately  
with the complexity of its task environment.  Here this hypothesis is  
tested by evolving robot morphologies in a simple environment and in  
more complex environments.  More complex robots tend to evolve in the  
more complex environments lending support to this hypothesis.  This  
suggests that gradually increasing the complexity of task environments  
may provide a principled approach to evolving more complex robots.
