Re: [computer-go] Me-first search



Yes, I think Petri is right.

Thanks, as always, to everyone on this list -- it's an enormously valuable resource. (Thanks also to the two people(?) who sent me the Saito paper.)

Now back to reading up on partial-order planning...

Looking from pure what we trying to accomplish this looks like the killer heurestic and null-move pruning.

Just more than one null-move. Obviously one would get more killer moves into list of killer moves.

This sounds just like Lambda search. On 6/19/05, Peter Drake <drake@xxxxxxxxxxxxxxxxx> wrote:
In tactical search, the defender is trying to build a certain structure (roughly, two eyes) and the attacker is trying to prevent this. I believe other placement games like Hex and Go- Moku also have this property, but Chess (largely) does not. This constructive property of the game suggests an interesting search strategy: first find out how I could accomplish my goal if the opponent kept passing, then consider potential countermoves and try to "repair" the plan. This would allow us to abandon some searches very early ("I can't make two eyes no matter how many moves I get!") and could greatly narrow certain others ("If I get to make these three moves, I'm alive, so you have to stop that."). Does anyone know of work on this? Obvious fatal flaws?
