Hey guys,

Are any elements of the controller (or "brain") encoded in the genome? 
From my reading of Chris' thesis, I can't see any.

Thanks,
Martin

I think the mission parameters are evolved, but general purpose
controllers are used, designed to work for all the evolved robots.

The "task parameters", which belong to either the high-level simulation
code or self-contained components (e.g. controllers or trajectories) are
encoded in the genome.  The main limitation is that only a fixed number
of parameters are encoded for a given problem; there's (currently) no
facility that allows for variation in length (or topology) of the task
parameters.  Adding some other representation for controller/brain code
wouldn't be that big a deal; you'd just have to change the portion of
the genetic operators that works on the task parameters (currently
uniform crossover).

Cool.  Thx.
