In summary, the conversation suggests using two programs that play randomly against each other to gather statistics on different values of komi in the game of go. This method may not accurately determine the "right" komi that leads to a draw, as proper play takes into account the komi in moves. AlphaGo has also played many games against itself to determine a suitable komi value for its level. Different levels may require different komi values.

I've just thought of a way to get the right komi in the game of go.
Let 2 programs that plays randomly play each other millions of times, for different values of komi. A game should take less than 1 second I guess since there's basically almost no computing process for each move.
Then "make statistics" out of those games. For example, for what komi value is the higher % of jigo reached?

Is this realistically doable? Would that be accurate?


For those who don't know what the komi and jigo are:
Komi is the points the player that plays white gets at start to compensate that black plays first. The "right" komi should be the komi that leads to a draw (called jigo) if both players play a perfect game.
To give you an idea, komi is generally taken as 6.5 in KGS go server. They don't take an integer because they want to avoid draws.

I've just started learning to play Go so I am interested in this too! Any ideas?

Random play doesn't show the advantage of a player with non-random play.
If it would, you would not have to test different komi values, you could check the distribution of point differences and find the median. This doesn't work with proper play however, as the players can take the komi into account in their moves.

AlphaGo played many games against itself, it should be able to find some reasonable komi value for its level. Other levels will need other komi values.
 

FAQ: Determining the right komi in the game of go (for 19x19 board)

1. How is the komi determined in the game of go?

The komi in the game of go is determined by adding a set amount of points to the score of the second player. This amount is usually determined by the size of the board and the level of play. For a 19x19 board, the standard komi is 6.5 points.

2. Why is the komi necessary in the game of go?

The komi is necessary in order to prevent the first player from having an unfair advantage. Without the komi, the first player would have a significant advantage due to their first move.

3. Is the komi always the same for every game of go?

No, the komi can vary depending on the level of play or specific rules being used. Some tournaments or matches may use a different komi, such as 7.5 points, to create a more balanced game.

4. How do you determine the best komi for a specific game of go?

Determining the best komi for a game of go is a complex process that involves analyzing previous games, player skill levels, and other factors. Professional players and computer programs may also be consulted to determine the most appropriate komi for a specific game.

5. Can the komi be changed during a game of go?

No, the komi is set at the beginning of the game and cannot be changed during play. It is an important aspect of the game and altering it mid-game could significantly impact the outcome and fairness of the game.
