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

[Teo Swee Ann]

I would like to add that, winning is not transitive: If A>B>C, it doesn't
always mean that A>C, sometimes; at least in Go, where ">" means wins.

Perhaps what we need is to show that A > (all X, where X <= B), then we can
conclude that A is "transitively stronger" than B, with reference to a
specific set of X's. 

Perhaps if we define this set of reference opponents, we can then
incrementally improve the strength of the Go programs, slowly but
definitely.

Hi,
I'll just answer the non-gnugo-specific question :-).

Yes.

No, tuning against just one opponent is risky.
Instead set up a tournament of 3-4 programs with different styles. (Or
the simpler way to do that is to put it on cgos:
