Summarized if you don't want to read the PDF: As for a simple
technical overview, there is 2 discussions important.
First one is the interview i had with many of the top researchers at
Second is the huge discussions on rec.games.chess.computer
Not sure whether google indexes those years, otherwise you will be
able to find it at altavista.
The thread is called something that Deep Blue should be looking ahead
like 18-20 moves (plies) instead of the 10-12 they got
(which was similar to the top engines in 1996-1997).
There i claimed that with that huge nps and what i saw in my program
adding modern algorithms, 18-20 moves (ply) would have been possible
to look ahead, as i saw how it was possible to get branching factor
3.0 to get 1 move (iteration) deeper.
After months of discussions on RGCC where majority of scientists
spoke out that it was total impossible to get a branching factor
like that (time to get another ply deeper), i got a surprising
Regrettably it was a private e-mail yet it was written by Frans
Morsch, at that point the reigning world champion. As usual no public
yet he reported that the branching factor of Fritz was 2.8 to get 1
So the most optimistic report and prediction of what was possible was
by Frans Morsch. As he saw 2.8
Todays branching factor of most top chessprograms is UNDER factor 2.0
in time to get 1 move (iteration ply depth) deeper search.
No one had predicted THAT in 90s.
If we would extrapolate that onto cryptography then some government
officials, when realizing that, will get very sick of worry.
