- Greg:

-
- As I had mentioned earlier, I believe that function identification using
- genetic programming (a la Koza) would be a useful way of examining this
- relationship including all the aspects of the cursor mentioned by Greg.
-
- Bill, can you send me some cursor-handle data from a well-controlled
- tracking task? I know that I can generate this myself using Demo1 and
- Demo2, but I don't know how to pull out the numbers. The first 2/3 of the
- data could be used for curve fitting then the last 1/3 used to test the
- model.--Gary
