[gnugo-devel] How to change the influence function?

[tk424]

Hello,
 
I am trying to implement a new influence function in GNU Go version 3.6.
I have two questions about this issue.
 
The first question is how to prove the new influence function is better the old 
one.
I believe it can be said the new influence function is better if the new GNU Go 
wins more games, in average, than the old one. The rest of the parts will stay 
the same.
In other words, this new influence function should be compared from self-play 
(old influence function vs. new influence fn).
Does this sound reasonable? Any comment will be appreciated!
 
The second question is more practical.
Could anyone tell what part in the source codes should be modified?
I have no experience of working with influence function, setting up a 
self-play, and counting the number of wins.
ANY input will be helpful...

After reading the GNU Go documentation 13. Influence function 
(http://www.gnu.org/software/gnugo/gnugo_13.html), I was trying to understand 
engine/influence.h and engine/influence.c.
But it's all puzzling to me.
 
Thank you in advance!
