Does anyone have references on using genetic algorithms to design digital 
filters? I've started using this method, breeding pole and zero locations, 
and evaluating the fitness of the resulting filters by finding the RMS of 
|H(z)|-Ideal(z) over 0<z<pi.
   This technique works well, but I think I could improve it with a better 
fitness function. Ideas?

	You could multiply (z domain) your fitness function
by a weighting function.
