Mate solving test (now with positions)

[Jouni]

I took 100 random positions from Chest database (mostly compositions):

I gave engines 30s to find written mate. Results:

Houdini 1.5 - 45
Critter 0.90 - 39
Rybka 4 - 31
spark 1 - 29
Stockfish 1.9 - 24

For comparison Chest/autoturbo 43. But there's problem: engines find in some positions shorter mate and they are correct! E.g. position 10 is actually 8x, 17 is 10x and 30 is 11x. But anyway Houdini is great mate finder.

Thanks for this info, Jouni!

I could confirm these 3 wrong mates now:

If you find (or already have found) any other wrong mates in the ChestUCI database, then please let me know, because of course I would like to keep my database as correct as possible!

Hi Franz,
I find wrong mates in ChestUCI.epd. I send you my times and parameters:

I find wrong mates in ChestUCI.epd. I send you my times and parameters:

Thanks Ignacio, very good job!

I'm really shocked about so many wrong mates, so probably I shouldn't trust the matedepths of problems I find on internet sites so much. The problem is that additionally searching for shorter solutions is quite time-consuming on my old and slow notebook, so I don't always try it.

I'll fix all those problems in my database and update it tomorrow,
thanks again for your great help,
Franz

More wrong mates and my results:

WOW, just when I was ready with the first set there's again a new one.
It seems there are lots of wrong mates in the usual problem servers on the internet.

BTW, some of your solution times (especially in brute force) are really incredibly short, almost unbelievable! What CPU (and MHz) are you using?

Here are the correct solutions on my Celeron/400:

I have a Q6600 2,4 Ghz with 4 Gb. RAM Windows 7 64 bits. Almost 3 years old!.
And yes, there are lots of wrong mates in the internet.
Merry Christmas.

Fortunately I don't have to pay for each wrong mate, otherwise I would soon be a poor man.

Thanks again,
