Brainfish, a new concept of a chess engine

[Ozymandias]

here's another example showing there's nothing new
under the sun, a Stockfish (playing on Fics) having a book
with six billion positions

I know of no software or book format that can handle, or compile a book, with that much data.

You can use Aquarium book adapter, with a book fritz,

in terms of size, my book for correspondence has almost 35 gigabytes, and rising...

hello ,great engine.how do you set up the "book path"folder? and how do you use it? thank you

Usually you have to configure BookPath in the Engine setup of your GUI, where all parameters of your UCI Engine are displayed.

There you have to enter the exact path and name of the book file Cerebellum_Light.bin which you downloaded and unzipped from the BrainFish Website.

For example if you unzipped the file Cerebellum_Light.bin on drive d: in the Folder Cerebellum_light_160728, the correct path would be d:\Cerebellum_light_160728\Cerebellum_Light.bin. If the file is in the same folder as Brainfish.exe, the name Cerebellum_Light.bin in BookPath should be enough.

Hi Thomas
Maybe you should explain it to him in Pictures !

If you use Arena, you an easily debug the UCI conversation.

For me, it looks like this:

35 gigabytes?! Holy crap... you should go commercial and make some cash!

I was talking about number of positions, size depends on the format. For example, ctg gets kind of big, I wouldn't even try my DB there.

Another metric which is cross-format, is number of games.

[velmarin]

Positions are approximately 10 million.
Chessbasse has no problems with these sizes, but it is highly recommended to make backup to extend it. A crash and everything disappears.

Actually, that's 10 million games, the number of positions will be much higher, but nowhere near 6 billion.

6 billion, I've read 6 million, yet this is a reference book, which avoids to consult databases and makes time.


I have now followed the link, sometimes the translator removes the links.
6 billions...

Code: Select all

 By now ArShah has computed and stored over 6 billion of chess positions running the cluster. This is a small number and it is quite achievable to compute and store over thousands of billions chess positions with ArShah.
