SPCC: EAS-Tool major update
Post by pohl4711 » Tue Nov 15, 2022 12:38 pm

I released a major update for the EAS-tool (Engines Aggressiveness Statistics-tool):

There are now 2 tools: The EAS-tool and the Gauntlet EAS-tool: The EAS-tool evaluates all played games in a source.pgn-file of all engines/players. The Gauntlet EAS-tool only evaluates the engine/player, which played the most games in the source.pgn file. The Gauntlet EAS-tool is IMHO a good thing for engine-developers, when they test their engine-dev-version vs. several opponents and are just interested in the EAS-score of their own engine...or for analyzing human players (search one player in the Megabase and calculate the EAS-score, without doing so for all of his opponents).

The scoring-system of the EAS-tools was complete rewritten and improved. Please check the ReadMe-File in the EAS-tool download for full explanation, because meanwhile the scoring-system got really complex...

Download the EAS-tool V5.2 on my website or right here:
https://www.sp-cc.de/files/engines_aggr ... cs_tool.7z

(The EAS-ratinglist on my website is already updated with the scores of the new EAS-tool)

SPCC: 750000 clicks and a new tool released
Post by pohl4711 » Sat Nov 12, 2022 8:21 am

My website reached 750000 clicks/visits !!!
I never expected so much interest in my little website and my computerchess-projects...

As a gift for the computerchess-community, I release a new tool: The Interesting Wins Search Tool.

https://www.sp-cc.de/files/interesting_ ... ch_tool.7z

The 2 output-files of the IWS-Tool contain different types of wins:
interesting_wins.pgn contains:
1) Queen Sacrifices, followed by
2) 5+ PawnUnit Sacrifices, followed by
3) 4 PawnUnit Sacrifices, followed by
4) 3 PawnUnit Sacrifices, followed by
5) 2 PawnUnit Sacrifices, followed by
6) 1 PawnUnit Sacrifices, followed by
7) Games, ended before endgame (material) was reached, followed by
8) Games with material imbalance (Rook vs. Bishop and 2 pawns for example)
very_interesting_wins.pgn contains: same as above, but without category 6 and 8, because, if the IWS-Tool is used on huge databases, the interesting_wins.pgn-file can be very huge, too.

The games in the output-files are sorted in 2 ways:
First: The games are sorted by categories (category 1 is followed by category 2, 3, ... etc.).
Second: In each category, the games are sorted by length (0-19 moves, followed by 20-29 moves, followed by 30-39 moves... and so on, up to 120 moves and beyond). So, in each category, the shortest wins are at the beginning and followed by the longer wins...
And each games gets a new Annotator-Tag, so it is clear, which category the game belongs to.
The IWS-Tool does not output any statistics, because I wanted the tool to be as fast as possible.
And - believe me - it is VERY fast! Filtering my SPCC-ratinglist gamebase, which contains 193000 games, only takes around 3 minutes on a modern PC (!!!). If you are interested in statistics, you can, of course, use my other free tools: EAS-Tool, Sacrifice Games Search Tool and Short Games Analyzer Tool.
So, the IWS-Tool can be used to filter all interesting games out of each pgn-database very quickly in a single pgn-file, cotaining the interesting wins very well sorted and annotated.

Human Beats Top Go Computer
Post by towforce » Thu May 04, 2023 7:36 pm

Kellin Pelrine, an amateur Go player, and his team uncovered weaknesses in the play of the top Go computers - a mistake a human simply wouldn't make (misunderstanding the nature of a group of stones). They built a program that exploited this weakness, and it consistently beat the top Go program.

How did chess pieces get their names?
One player’s pawn is another’s farmer. And at one time, the queen was a rather powerless virgin.

Updated May 12, 2023:
SugaR AI SE was removed from my ENET-2023 list. What is the reason? I heard that the search code of SugaR AI SE is 1:1 identical to Stockfish dev, which was released at the same time. I compared the code myself and got the same result. I don't want to have a duplicate Stockfish dev in the list. I am therefore now also surprised that the author of SugaR AI SE only mentions himself as the author. With a 100% Stockfish dev search code, the other SF developers should also be mentioned.

Dear Edward,
i simply forgot to update the authors, as can be seen even in new versions only the Iccf version reports the authors

I don't get it... what kind of test is this? Is it a tournament? Ni specifics about the test here.

And he wrote about SugaR AI but left other Stockfish clones inside: ShashChess, CorChess, Crystal, SugaR Iccf, Eman, Blue Marlin and Dark Sister.

I think the 'test' is to solve as many problems out of the 110 provided. The epd was made available somewhere but since its of no interest to me I didnt download the file. I think Eduard was more concerned about attribution - I dont know if the ones you mention include the SF Team as authors. I dont use those engines.
