| I belonged to an Alvey project called Adaptive Intelligent Dialogues
| in which we investigated Adaptation.  During the course of this 4 year
| project we produced a taxonomy of adaptive systems.....
| ---------------------------------------------------------------------
| Levels  Computers	Evolution	Features
| 
| 0.5	Tailorable/	-		Deferred selection
| 	Adaptable
| 
| 1	Adaptive	Tropism/	Apparent Learning
| 			reflexes	(i.e. fully determined by design)
| 					Discrimination
| 
| 2	Self-Regulating	Operant		Learning; Varied responses
| 			conditioning	selected for different situations;
| 					Evaluation by trial and error
| 
| 3	Self-Mediating	Internal	Planning, Problem Solving;
| 			evaluation	rule-mediated representation;
| 					Initial evaluation internal to
| 					system
| 
| 4	Self-Modifying	Abstraction	Evaluating the evaluation;
| 					Generalisation; Meta-knowledge

I had to sit on this for a while before answering.  I don't understand 
all the terms, but the basic idea seems at least interesting.  Coming
out of a 4-year AI project gives it a lot of credibitity.

In terms of this taxonomy, where would the system of evolution fit in?
It's at least a 2, since it does trial and error in a big way.  I'm not
sure it goes any higher, because it doesn't do any forward planning. 
But on the other hand, it has in the past modified its own memory
structure, so it might qualify as a 4.  Any ideas?
