Quoting Michael Williams <[email protected]>:
I wonder what would happen if you counted jigo as a loss for both
players...
Interesting, it would then avoid all lines that are likely to lead to a draw.
The problem is that it then not be able to see any difference between a jigo
and a loss which may be a problem in a position which is a clear jigo. What
happens deeper in the tree does not matter, if there is only a few jigo
candidate moves and many losing moves, the program will often pick a losing
move.
I had almost posted that on yesterday, but I did not know whether you
could disconnect the result for W and B. Otherwise, the easiest hack to
discourage jigo without making it like defeat is:
count jigo as victory for each player say 30% of the time, and as defeat
for W otherwise.
