Dear Helder:

I am happy to send you the draft you requested. Also enclosed is a draft for a
related paper, to be presented at the Fourth International Joint Conference on
Artificial Intelligence.  Since the latter paper is briefer, more descriptive,
and more elementary, I suggest you read it first.  My current research is in
harnassing BEINGs to make simple "discoveries" in elementary mathematics.
If your work is relevant to mine, please keep me informed as to what you are
pursuing.
