RE: [computer-go] Mathematically sound rules for determining whenthegame is over

I would add a rule: you have a fixed amount of stones to play the game.

Go sets usually have half the amount of board intersections of each
color, you could limit to the amount of board intersections of each
color.

Subject: [computer-go] Mathematically sound rules for determining when
thegame is over

Hello,
I've been trying to figure out a good set of rules for unequivocally
determining when a game is over. Ssince mutual passing only works when
both players agree on the score, what happens if they never agree,
regardless of how far the game progresses? If the rules of go are to be
logically sound there must be a way to determine the score from the
rules of the game when it has been fully played out. 

What I've come up with is: (I'm assuming chinese rules with super-ko
rule.)
* The game is over when neither black nor white have any valid moves
except moves that put one of its own groups into atari.
* When the game is over your score is the number of stones of your
colour on the board and the number of empty intersections surrounded on
all sides by stones of your colour.

This seems to work; when all groups have only two one-stone eyes or are
in seki the game is over and the score is easy to determine. But are
there any problems or inconsistensies with the standard rules that I'm
missing?

Regards,
David
