MGA GoTD
MGA GoTD is a free open source program for running small to medium sized
Go tournaments
(16-80 players). It handles registration, pairing, and reporting results. GoTD has a
simple easy to use interface. It runs on Windows, Linux, and Mac. Currently used by
the
Massachusetts Go Association.
Running the Program
This program requires the Java Runtime available from
http://www.javasoft.com. Once the Java
Runtime has been installed you can run GoTD as a Java WebStart program. Just click
here.
You can also download it and run it as a standalone program on the
SourceForge summary page.
Running this program outside of JNLP gives you the additional options to
specify the number of rounds in your tournament and the value for komi.

What is it?
The tournament director is a program written to run the quarterly handicap tournament
of the Massachusetts Go Association. The program can be used to run any Go tournament.
The program will handle player pairing, tournament ranking, and separate player bands.
It saves in the
AGA tournament reporting format.
Setting Bands
The bands dialog makes it easy to create an upper and lower band for larger tournaments.
Seeing Results
The results dialogs makes it easy to see who won the tournament. The bottom five players
makes it easier to determine a player to pass a specific round.
A Real World Example
GoTD is used to run all tournaments at the Massachusetts Go Association. They maintain
a page describing their
tournament procedures. It
is an excellent resource for anyone running their own Go tournaments with or without GoTD.
The Pairing Algorithm
GoTD pairs players with two goals. First is to make sure there is a clear winner at the
end of the tournament. To achieve this the program pairs winners with winners and losers
with losers. As the tournament progresses this will result in an increasingly smaller set
of players who have won all of their games. At the end of the tournament only one or two
players will have won all of their games and they are the winner.
The second goal is to minimize the number of handicap stones. In each round the software
will try to pair the players with the closest ranks. Tournaments are more enjoyable for
everyone if a 15 kyu plays a 14 kyu instead of a 5 dan.
Determining a Winner
At the end of the tournament there will be a small number of players who have won every game.
If there is only on player like this then they are the winner. However, most often there
will be more than one player with a perfect record. In that case the winner is determined
by the sum of opponents scores. Each player with a perfect record is given one point for each
game their opponents won. The player with the most points wins.
