Go programs often analyse the tactical status
of blocks (sometimes called strings) of stones. A block tactician performs some
local search and then assigns the status ALIVE, DEAD or UNCLEAR to a
block.
I have the problem how to treat double threats in
this context. Let's say that two blocks are threatened and the defender may
choose which block he wants to give up. Then the block tactician might
treat the two blocks as "half-DEAD"
or it might treat the bigger (or "more important") block as ALIVE
and the smaller one as DEAD. None of these solutions is really
satisfying and some special treatment seems to be necessary.
Since the situation is often too complex for a
global quiescence search, a good solution of a direct evaluation of double
threats might be helpful. Does anybody know about a good solution
of this problem?
