You're right. That's why I'm asking if there are engines specially designed for puzzle solving.Nay Lin Tun wrote: ↑Wed May 06, 2020 5:08 amIt is good to know that none of the top engines waste time in searching such garbage positions.
Finding the best move in chess is like searching the gold. If you dont filter ( pruning in engine term), you are less likely to find the gold and find more garbage.
Any engines good at solving puzzles like this?

Re: Any engines good at solving puzzles like this?
There are such things, but none can solve them all.
Sting is especially good at some categories of problems, and Houdini Tactical is especially good at some categories of problems.
A friend recently showed me that Bluefish XI-LP FD with special settings (Tactical=2; defensive=off) is especially good at a broad category of difficult problems, but I tried it on your problem and it did not solve in 1/2 hour.
Crystal, Corchess and Sugar are all pretty good.

Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Re: Any engines good at solving puzzles like this?
cur-dev-Bluefish with default settings, looks very promising here. It also found a big score in under 3 minutes - I got smarter this time and will let it search overnight.
I haven't posted the updated sources yet to Github , it looks like the official stockfish will soon have Large Pages - so I'm waiting for that before I upload it. Previous versions of Honey etal had Large Pages which was based on Brainfish large pages, so obviously I will flip it over to the Stockfish large page code once they have it approved. No real difference in functionality, but it will be clearly cleaner code and speedup official stockfish by 5 to 8 % depending on your hardware.

I haven't posted the updated sources yet to Github , it looks like the official stockfish will soon have Large Pages - so I'm waiting for that before I upload it. Previous versions of Honey etal had Large Pages which was based on Brainfish large pages, so obviously I will flip it over to the Stockfish large page code once they have it approved. No real difference in functionality, but it will be clearly cleaner code and speedup official stockfish by 5 to 8 % depending on your hardware.

OK.

One man's trash is another man's treasure.Nay Lin Tun wrote: ↑Wed May 06, 2020 5:08 amIt is good to know that none of the top engines waste time in searching such garbage positions.
Finding the best move in chess is like searching the gold. If you dont filter ( pruning in engine term), you are less likely to find the gold and find more garbage.
I adore composed positions like this one, because it is an art form.
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Re: Any engines good at solving puzzles like this?
I apologize if I sent you off on a wild goose chase. I have a modification that only affects positions with mobility extremes. It is the only functional change that I make to the eval. I made an s-curve to help when the mobility is super-cramped or wild-exploding. I use it to alter how null move works.zullil wrote: ↑Wed May 06, 2020 12:58 pmOK.

It will also prune drastically less when the number of move choices falls into the teens.
So, for instance, if the value of R was 6 plies and there are 5 move choices, this function will return 0.395363 and the value of R will be 2.372178 instead of 6.
The reasoning being, if there are only a few move choices, we have time to examine them more carefully.
Since the average branching factor in chess is about 36, on the average, this function does exactly nothing. But when we are ultra-cramped it will allow solutions to problems that are otherwise out of reach.
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Re: Any engines good at solving puzzles like this?
No problem, Dann. I learned that Stockfish-dev will eventually solve this, as I expected it would. Just very slowly.Dann Corbit wrote: ↑Wed May 06, 2020 7:31 pmI apologize if I sent you off on a wild goose chase. I have a modification that only affects positions with mobility extremes. It is the only functional change that I make to the eval. I made an s-curve to help when the mobility is super-cramped or wild-exploding. I use it to alter how null move works.zullil wrote: ↑Wed May 06, 2020 12:58 pmOK. So you weren't using an unaltered Stockfish-dev, which does appear to find the solution, maybeDann Corbit wrote: ↑Tue May 05, 2020 11:03 pmLooking at the position (with extremely limited move choices for both sides) I think it was my mobility tweak that made the difference.zullil wrote: ↑Tue May 05, 2020 10:24 pmI'll try Stockfish-dev (unaltered) again. Maybe my first run was unlucky. Or your was very lucky.Dann Corbit wrote: ↑Tue May 05, 2020 10:18 pm Current code seems to solve it fairly quickly, even without altering the null move status.

As you can see, it will prune 1% more if there is a huge number of possible moves.
It will also prune drastically less when the number of move choices falls into the teens.
So, for instance, if the value of R was 6 plies and there are 5 move choices, this function will return 0.395363 and the value of R will be 2.372178 instead of 6.

Did you ever have your modification tested at Fishtest? I guess it would be more-or-less Elo-neutral. But who knows.

Re: Any engines good at solving puzzles like this?
I posted an early version of it, but it was too complicated and caused an Elo loss.
My purposes for chess analysis are quite contrary to game play.
I want the best answer, even if it takes more time.
So I don't bother pushing my ideas on fishtest much.
I have also found that there are a lot of rude, disagreeable people there.
So I generally keep my nose out of that place.
