new A* optimization: worst-case pruning
...
i'm not sure if this has been described in the literature exactly but it
is similar to existing branch-and-bound techniques.
it doesn't speed up the search directly (the number of visited nodes is
the same) but it does cut the queue length down by an order of magnitude
and shave a couple seconds off of day 16, presumably due to reduced memory
pressure or something.
