Re: Bright Revelation (after Round 20 of 30)

Am I correct in stating that Bright is private engine, and that only a few individuals besides the author have access to it? Will it be available soon, either commercially or freely?

Re: CCRL update (28th September 2007)

Hi Graham,

Why isn't Strelka on the list of "killed" engines? It seems to me that she is not an asset to your rating lists.

Thanks Edsel. Any luck solving the "losses on time" problem?

Regards, Graham.
The "loses on time" bug seems to have disappeared.

Re: Movei "peppers" Fruit

The opening selection has an unusual distribution: ECO A = 21 Games (42.0 %) ECO B = 9 Games (18.0 %) ECO C = 10 Games (20.0 %) ECO D = 9 Games (18.0 %) ECO E = 1 Games ( 2.0 %) I would want to see the pgns before I take this result seriously. I suspect there were repeats of the same opening.

Re: Collecting games with players at specific FIDE ELO level

I expanded my utility minElo to perform extractions based on 2 Elo ranges. I think it works properly, but I cannot guarantee it. So please pm any errors to me. Here is the download link: http://www.orbitfiles.com/download/id1843401880.html Here are some usage examples: To extract all games with BOTH...

Re: Collecting games with players at specific FIDE ELO level

minelo only works with pgn files. It is my understanding that chessbase proprietary data files can be converted to/from pgn files through a chessbase gui or through their proprietary database program.

pgn files are not proprietary and that is why I only work with them.

Re: Collecting games with players at specific FIDE ELO level

I have a utility tool that extracts games where BOTH players are at/between specific Elo levels. I don't know if that will help you since you only want ONE player at/between a specific level. The utility tool is called "minelo" and it is easy to use in a Dos command window. For example: minelo alpha...

Re: CCRL update (1st September 2007)

I think that draw analysis is very bad to decide if engines are in the same family. I see no reason to assume that there will be more draws between program A and itself relative to draws between 2 other engines that have the same playing strength. For example I can imagine a small number of draws b...

Re: CCRL update (1st September 2007)

Hi Kiril, If both "ponder hits" and "draw analysis" point in the same direction, then there are likely to be 2 similar thinking engines. Are there any "control" experiments with "ponder hits" to establish reference points for the stats?. Like calculating "ponder hits" with two identical engines, or ...

Re: CCRL update (1st September 2007)

Hi Kiril, "Ponder hits" and "draw analysis" both attempt to see if 2 engines think alike. Each is not definitive proof as each can contain inaccuracies. But perhaps together, they are more persuasive than either alone. "Ponder hits" as I understand it, can have inaccuracies due to the differing amou...
