Re: [gnugo-devel] Re: [computer-go] SlugGo v.s. Many Faces

[Don Dailey <drd@xxxxxxx>]

I suspsect that this method will  be equally effective against a 1 kyu
player, just my opinion.  Even though  it does seem at first glance to
be hard  core "opponent modeling"  I can imagine  what is going  on by
comparing to my own program.

There are many times where my program is "torn between" two moves, one
which is pretty  bad and one that is right.   Even something simple to
resolve many  of these cases would improve  the program significantly.
Some of  them are not easily  resolvable with simple  heuristics but a
"peek around the corner" would help significantly.

   I am afraid, that there are many situation where the move which 
   seems to be the second best at first sight is much better then the 
   first. (Or the first leeds to a trouble, which is the same... :)) And 
   when this happend at 3rd ply, then searching the wrong line in 16 
   deep is worthless. It is not supprising that it could be stronger by 3-
   5 kyu against himselt, but it is interesting for me that it is 
   significantly stronger against Many Faces. I guess that 16 ply 'very 
   narrow' search can not help more then 1 kyu against human.

   But your result are interested anyway, because no one knows the 
   result.

   May I ask the averages branching factor at the 1st ply ? If it is 
   significantly less then 72, then do other processors nothing ?

   Best regrads
