Re: Bug in Crystal ?

Post by jhellis3 » Fri Jun 05, 2020 8:14 pm

Ok, here is what is going on...

Crystal is allowed to search normally on non-draw tb hits, and thus display the engine eval (typically mates) over the TB score much sooner. However, in very difficult to resolve situations, such as the fen posted you still get the engine eval, but it displays drawish evals because it has not actually found the 5 man TB hit which is very far away and doesn't recognize the position as generally winning otherwise.

Now, if there were multiple winning paths, the score would more or less always be correct because the correct values are stored in hash and any lower than TB score would trigger the appropriate TT cutoff with a TB score.

In this case, there is only one winning path Rd6+, Rdxa6. Since these are the PV moves, they don't take the TT cutoff and are searched normally by the engine. And since they are the only winning moves, there are no other TT cutoffs to bump the score up.

The upshot is that this can not hurt actual play, as any time the best move was not the PV it would instantly trigger a TT cutoff and become the PV. Thus, optimal play & analysis is preserved. The only potentially bad thing that could happen is a very unlucky time cutoff in actual play.

"Fixing" this has consequences: Crystal would probably become slightly slower to find mate in general, slower to resolve to shortest mates, but quicker to display won/lost TB scores.

It doesn't really matter to me either way. In general, the situations where the engine can not see a TB win as at least good are quite rare, and the subset of those positions with singular winning paths and high DTZs rarer still. Anyway, I am happy to adjust the behavior or not if there is some consensus as to what is best.

Thanks for the detailed explanation, even if I don't understand it fully.
As for my personal pov I'd say leave it for good, if it's for this single one position only, where the way to 6men position is very short and clear, even if then decision between draw (74...Raxa6?) and win is still to be made then and there.

(Edit: here I had some other sentences written already before, that were wrong)
That's what I'd say, if chosing the right move would happen anyway after 73.Rd6+ Ke7, but (tried only new one "a" so far now) Crystal doesn't prefer 74.Rdxa6! then, instead:



Analysis by Crystal 050620 64 POPCNTa:

74.Ra1 Kxd6
= (0.00) Depth: 7/3 00:00:00 16kN, tb=251
...
74.Ra1 Kxd6
= (0.00) Depth: 29/3 00:00:01 9335kN, tb=620708

That's after minutes of waiting, no more output line after this one appeared.. It was started with already full hash, but I can't wait now any longer or repeat with empty hash, edit- time would end. I wanted to delete this posting, but it didn't work, probably somebody is alread answering.

And what I still don't understand: Crystal evaluates the position after 74.Rdxa6 with 97+ correctly at once having it on board, why can't it "see" this one on disk stored 6men just 1 ply before?
Peter.

This one was started with already full hash from pondering on starting position before, so I gave it another try started with empty hash again, this time Crystal got it right, even with some instability of eval again, but having the correct move in output only all the time:

Re: Bug in Crystal ?

Crystal evaluates the position after 74.Rdxa6 with 97+ correctly at once having it on board, why can't it "see" this one on disk stored 6men just 1 ply befor
It does see it; it is just allowed to search beyond the TB hit. In most TB win situations, the engine will also score them favorably, and mate is not too far away. In order to resolve potential mates, the engine is allowed to search beyond the TB hit. In this case, there is no immediate win, and the engine eval is drawish, so in order to display a winning score it needs to find the next TB hit, which with optimal play is 75 ply away. TB is only probed on zeroing moves. The search, understandably, isn't finding the 75 ply away TB hit, thus displaying a low score.

Anyway, I *think* I have a solution which will provide the desired result without interfering with mate resolution too much.

If you don't mind testing 2 more versions d & e....

For me, both versions are good.
They give a winning score to 71.Kg4.
