SWCR: Random Book for Shredder Classic GUI v. 5.11 available

[Frank Quisinsky]

Hi there,

I think the latest version is good enough now. I have no more idea to make more optimations. Per Random around 3.000 positions will be play. Each of the positions are checked with 80.000 SWCR games and per analyzes by 4 engines with 1 minute per position on 4 cores.

- ECO segmentation now fully OK.
- no fast remis games will be produced.
- no fast win games will be prodcued.
- many openings will be play.
- double games with probability in per mille region.
- for chess engines critical positions are deactivated (example a lot of french or dutch openings ... engines with black produced here a lot of fast lost games).

ECO segmentation
After the first 734 games with book version 5.11:

ECO A = 209 Games (28.5 %)
ECO B = 183 Games (24.9 %)
ECO C = 113 Games (15.4 %)
ECO D = 128 Games (17.4 %)
ECO E = 101 Games (13.8 %)

Best GM games segmentation for compare it with my book.

ECO A = 1512 Games (29.5%)
ECO B = 1116 Games (21.8%)
ECO C = 634 Games (12.4%)
ECO D = 1110 Games (21.7%)
ECO E = 748 Games (14.6%)

This opening book isn't a special book for an engine. More or less it is created for testing engines.

- rating list
- tournaments
- long test sets

Project description in German language:

And so far available for Shredder Classic 4.0 GUI only. At the moment I am working on a Fritz GUI version.

On my webapge can be found a database with fast remis games too. I collect this games for my book optimations. This games I replayed for SWCR ratinglist and deactivated the lines in the Shredder Book.

My Shredder Book need my own settings. The settings can be see in *.jpg included in my download file.

It was not easy to create a good ECO segmentation with my Random concept. I need here a longer time for it. Example if I used the PGN without to do that ECO A = 41%.

Furthermore, Shredder should play the positions per random as a opening book. In this case the PGN file must be optimated and in Shredder GUI I have to set only prios for the ECO segmentation.

Have fun with this work!
I think it's now perfect with version 5.11 after a longer time of developement.

The idea was born for years in time I developed with Martin Arena. Arena have such an options (PGN-Random). With the Shredder GUI all isn't easy but possible with this opening too.

Best
