Life happened, I guess.

Some of them, I'm sure, had personal reasons for retiring, not related to chess.
In the Spracklins case, the "team" got divorced, and their project with Saitek
was not stunningly profitable.

Yes, I believe there is a creativity factor at work. In the early days of chess
programming, it was so exciting just to see a computer play chess at all. A new
idea could generate a whole re-write, and net you a huge improvement in playing
strength. Consider the change when Northwestern's CHESS went from ver. 4.2 to
4.5. Slate & Atkins added something new - a transposition table! This was big
and exciting! Would a chess program become unbeatable with this stunning
breakthrough?

Now, our software improvements are all rather normal, hardly edge-of-your-seat,
stuff. Software improvements have been hard to come by for many years (10-15).
As the chess program matures, you wind up working just as hard, for (generally),
smaller and smaller returns. You can't fight this - it's just the way it is. You
already eliminated the big bottlenecks in the first few years, only the smaller
one's are left to work on. As you say, the programmers aren't working with big
numbers now, it's little "decimal places". This may not be what attracted these
people to chess programming in the first place.

I think everyone would like to give their chess program one big push, at least
once, before they retire from working on it.

I think Bob and Ed are exceptions, and exceptional. You'll know when Christophe
no longer feels creative - he'll start saying that one's creativity can only
last for just so long! :-)

Hopefully, that won't happen for creative or economic reasons.

Good post - good jaunt down memory lane.

P.S. Bryant's Colossus was a checker's program. Played against Chinook several
times. Did it play chess also?
