The Clone Tournament

Post by Ovyron »

Now even tourneys are cloned! :lol:

Yesterday, Ray started a new tourney and asked what version of Toga should participate. I wanted Toga II 3.1.2SE Chekov to participate but went 5 hours too late! So I decided to make my first tourney a clone of his tourney but with this Toga, and with the difference that my tourney will have a greatly lower quality:

Athlon 2.1Ghz 32bit
Several GUIs
1'+ 7" with ponder off
64MB hash each engine
6-men online tablebases (Games adjudicated upon reaching 6 piece endings)
No books
Round robin each color, 112 games

To make up for that, I created new engine logos for all the participating engines:

Rybka 1.0
Fruit 2.3.1
Toga II 3.1.2 Chekov
Spike 1.2 Turin
Glaurung 2.0.1
Naum 2.0
Bright 0.2c
Frenzee Dec07

You can also try to guess what engines are going to end in 1st, 2nd and 3rd places (But if you are going to pick the same engines as another person, just do it on a different order.) Feedback appreciated 8-)

Thanks

Chekov is just Toga 3.1.2 SE with these settings:

[OPTIONS]
Verification Reduction=6
Futility Margin=125
Extended Futility Margin=325
Delta Margin=55
Quiescence Check Plies=2
Material=102
Piece Activity=103
King Safety=125
Pawn Structure=105
Passed Pawns=105
Toga Lazy Eval Margin=245
Toga Extended History Pruning=true

(Not the compile that made these the default but was slower.)

Thanks to Eelco de Groot for these settings ;)

Thanks for the link. This source for Toga 3.1.2SE compiles ok for me. I have never tinkered with Toga code, but i may try compiling a build with these settings as default.

:roll:

Ok, here is my "clone" tourney in Arena - Round Robin, "5 + 5", 56 games start 1.d4, 56 games start 1.e4, ponder off, 128mb hash.

Congrats, I hope that your compile is as fast as Denis Mendoza's ;) (I just tell the GUI to change Toga settings so I don't need to recompile.)

Well, i just don't trust the GUI. I'm not expert at compiling but i think my builds are ok.

By the way, great logos! i'm using them, except for Frenzee, in my clone tourney.

EDIT: If Toga wins this tourney, i'll give the credit to my build. If Toga plays like crap, i'll blame it on the chekov settings.

I'd forgotten that Feb08 had come out. But someone reminded me so that's what I'm using
