The great 40/120 Tournament

Post by krazyken » Wed Dec 24, 2008 12:42 am

Finished with Bikjump! It finishes a Little ahead of Alf.

Code: Select all

1: The Baron 2.23                     92.5 / 132
2: amundsen 0.70                      57.5 / 128
3: Beowulf v2.4                       49.0 / 132
4: BikJump v2.01 (64-bit)             43.5 / 130
5: Alf v1.09                          42.0 / 132
Bikjump has some bugs in endgame lookup, getting losses in drawn endings. It is also seriously sloppy with king safety. But it can get a surprisingly strong game from time to time. Amundsen 0.75 is being added in, it still seems to have problems with draws and executing a mate in 1. Toga is being pulled out because that build wasn't stable, I'm running some tests this week to find the best build to include. Mediocre 0.334 is starting stronger than 0.332 did.

Will be adding Arasan and updating Glaurung shortly. Possibly Grapefruit and Cyclone may be joining as well. Games can be found here, and extra games from engines that have been replaced or pulled can be found here.

Kenny,
I appreciate your tests and also the detailed reports you gave me through PM. I hope to get some spare time again soon to look at those Nalimov endgame lookup bugs and, thus, avoid giving away won endgames. Thanks again!

It's fascinating how wildly different Mediocre performs in different tests. And for some reason I usually get much better results when running the tests myself.

The only real difference between v0.332 and v0.334 is that Mediocre supports polyglot opening books now.

Next version should be better though, but it's a couple of weeks away (going out of town for a while now).

Hi Jonatan,

does this mean that the results of Mediocre 0.332 and 0.334 can be combined or should we still treat them as separate engines for rating list purposes?

Cheers, Graham.

I'd say combine them.

There might be some off-chance that the cleanup of the code (mainly rewriting comments etc.) made some unintended difference but most likely not.

Toga is being pulled out because that build wasn't stable,
I noticed that some versions of Toga on some compilers do not work well with some optimization settings. It would be interesting to understand this.

Toga is being pulled out because that build wasn't stable,
I noticed that some versions of Toga on some compilers do not work well with some optimization settings. It would be interesting to understand this.
Yes, it has come a long way from it's stable Fruit roots. It appears to be connected to the threading code, as reducing the number of threads increases the time between failure. I will try less aggressive optimizations to see where I get. Have you run many longer time control games with many threaded Toga?

P.S. The versions of DLT and Grapefruit on your site do not run at all with multiple threads on My mac.

Are they all really MAC compatible, Ken?

Perhaps you'd love to operate for Hamsters at CCT? See if you can get the Ok from Stefan for operator - Shredder.
