Dear Uri:
This discussion is becoming a kind of example of logic falacy. The issue
is not to state or to deny if programs have or have not a full
positional understanding , but to discuss if positional understanding is
or can be solve with other ways that the usually asked "knowledge". In
other words, the holes you ha spotted so well are one thing and to think
that those holes coul be filled with "konowledge" is another matter. Not
necesarily one is the product of the lack of the other. In my view the
esential factor here is the quality of the search algorythm and this one
is not, as you know, just a question of filling the source code with
tabels, functions, etc. In this, like in any other things, the point is
the mix and the best mix not ever is the greatest mix. Let me give you
an example: all the history of technology show that a the greatest steps
ahead were produce when some very comlicated and improved technology
gave way to another far simpler but superior in his use of energy. Never
steam locomotives were more stupnednour work of engineering that the day
previous to the arrival of the very simple electric motor. Maybe I am
wrong, but some lesson could be drawn from that in the field of chess
computers.
Shalom
Fernando
