Hi Aja,
PS. To which University will the Ph.D. thesis of Aja Huang be submitted?
Will the procedure be run in Taiwan or in France?
National Taiwan Normal University (NTNU) in Taiwan.
I see, thanks.
The procedure of thesis defense will run with my main advisor (Professor

Hi Aja,

That't interesting. Maybe I can have your doctoral dissertation for
reference about the writing style and overall structure?
That would be difficult and likely not so helpful:

Hello,
now I found time to read several sgf protocols
of KGS games played by BonoBot.
Here is part of the chat from a game between
BonoBot and Zen, which I find very interesting.

to combine one very strong and two normally strong bots.
Ingo.
PS. Majority voting (with 3 bots) in 19x19 go might be problematic
as you will have many situations with three different proposals. So,
you would need clever tie-breaking.

Hi Nick,
thanks for the information.
KGS seems to use a sub-optimal pairing program: ...
There are 12 participants.
How can you pit, in a CH-system, four of the five
strongest against each other in the very first round?
It does not use any knowledge of the players' strengths.
And if
One comment added:
In swiss tournaments, proper pairing for the first
round is the more important the larger the number
of players relative to the number of rounds.
(Typical case: number of rounds = c * log(number of players),
where c is a constant larger than 1, and log is meant for base 2.)
Hello Nick,
Suppose there are ten players, numbered from 1 to 10 in order of
strength. Is the proper round-one pairing
1 v 6, 2 v 7, 3 v 8, 4 v 9, 5 v 10
or
1 v 10, 2 v 9, 3 v 8, 4 v 7, 5 v 6?
I ask only out of curiosity, and in case I some day do the draw for a
non-KGS Swiss
Hello Nick,
You are proposing that the tournament should start by pairing strong
players with weak players, and claiming that this is more likely to
result in the strongest player winning the tournament. I don't see it.
A formal proof for the general case. Only special cases (for instance
Sorry, the first sentence in my previous posting
was incomplete. It should be
A formal proof for the general case IS NOT KNOWN.
Only special cases (for instance
with one top player, (n-1) semi-strong players, n weak players) have
been proven.
However, one can run some simulations to get
Hi David,
thx for sharing this info.
Did you see an improvement by the pondering?
How far did you spread the search in the pondering process?
Is there some paper describing standard ways of pondering
in Monte-Carlo environments?
