Asa H incorporates a number of learning mechanisms including "rule" chaining. At the lower level in the memory hierarchy Asa has chained together things like :
sense dock to right --> turn right --> sense dock forward --> move forward --> dock --> recharge --> charged --> back away
(see chapter 1 of my book Twelve Papers at www.robert-w-jones.com , book)
At higher levels in the memory hierarchy Asa chains together things like:
a production system --> a universal machine --> Turing equivalent --> intelligent
This is very similar to what occurs in the "creativity machines" that I studied some years back. (see Kans. Acad. Sci. Trans., vol. 102, pg 32, 1999) Asa's reasoning is more sophisticated, however, in that it may involve concepts of different levels of abstraction simultaneously.
