RE: [computer-go] M.Boon-Library

["Mark Boon" <tesuji@xxxxxxxxx>]

I'm currently in Teresopolis. I probably do still have it somewhere on a
backup disk, I can currently only find some sources on my laptop that may or
may not have been in there. Maybe the easiest is to ask Thomas Thomsen to
attach it to a message here in the mailing-list. That is if he kept a copy
of course.

Personally I think the influence module in there is THE most important one.
The ladder tactician comes second.

In regard to someone like Mick Reiss keeping quiet, I don't think it's fair
to blame him or anyone else for that. In general the Go community does share
ideas and that includes some of the 'pros'. But the word pro says enough,
these people need to make a living off their software. Without it there
would be even less progress in computer-go as there already is. And you
simply can't expect them to publish publicly what they're doing, it's
unreasonable.

Last, I didn't read all the posts about the hashing, as I think it's too
boring. I appreciate the academic value of the discussion, and aplaud that
it happens here. But as a pragmatic person (which I think you need to be to
make a full Go program) I see hashing of full board positions only useful to
store results of previous results computed by some other module, like a
tactical or L&D reader. The hash-key comparison and lookup are very cheap
compared to the calculation they replace, so it doesn't need to be
rocket-science. The quality of the hash-key only has to be good enough to
avoid collisions too often to be noticable. How many positions before it
becomes too likely a 32-bit key make two different positions compute to the
same value? I actually don't know the answer. Probably enough for most
applications (like Goliath), and when it's not you move to 64-bit. And when
you use stupid amounts of positions, of which I see no point as yet, there's
very little to stop you from using 128-bits.
