Matesolving test with SF18

[Jouni]

Code: Select all

Huntsman       421
SlowChess      339
SF18           265
PlentyChess    261
Reckless       257

This is improved test with 470 long mates. No mates from Chest database. No need to find shortest mate.

Can you post 17.1 and 17 please? Also SF8 just for interests sake?!
Thank you.

SF 17.1 got 263. I have not tested SF11. It's clearly best Stockfish in solving. Simply because node speed is 3x faster!

Well, Jouni, but then the results don't tell much more than but which one engine gives any DTM into output than the other ones do at certain positions, no matter how exact it is, isn't it?
I mean, I can say much earlier in many games but any engine does, that one side will checkmate the other one sooner or later, as long as I don't have to prove, how many moves that will take

Hi Jouni, how did you perform the test?

Do you accept truncated PVs? If so then I might have a pretty good entry for the list.

You can claim mate in at most 1000 moves when the engine evaluates the position as at least +40 maybe with no possible mistake because you are always going to mate in at most 1000 moves

I thought iniially to choose 100 moves but I was not sure that there is not some long tablebase win based on DTZ tablebases that is mate in more than 100 moves that the engine may evaluate as more than +40.
