Extracting quiet positions?

Post by cucumber »

Hello,

I'm looking for ways to extract quiet positions from an epd file while preserving existing comments, bestmove, etc., information. I have a few million positions and just need to get rid of the noisiest ones.

Are there any scripts or programs to do this? If not, does anyone have recommendations for the best way forward?

Thank you.

i did something like that a couple years ago.
i used the python-chess library. The documentation is here:

https://python-chess.readthedocs.io/en/ ... index.html

I used the parsing features to grab a FEN and then some other calls to see if any of the available moves were captures. i think i ignored positions that were checks as well.

I couldn't find my code but if i run across it, i'll post it.

I do something like mobat, but I use SQL queries.
I don't insist on no captures or promotions, so only one or two 'x' or '=' characters in a long pv are OK if the first or second move is not a capture.
The function looks like this:

Code: Select all

USE [Chess]
GO

/****** Object:  UserDefinedFunction [dbo].[Quiet]    Script Date: 2020-05-24 6:18:51 PM ******/
SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO


CREATE FUNCTION [dbo].[Quiet](@pv as varchar(256))
RETURNS bit 
AS 
begin 
   DECLARE @shorterby int;
   declare @FirstNode as char(16)
   declare @SecondNode as char(16)
   select @FirstNode = dbo.GetFirstWord(@pv)
   -- check for early captures
   if (@FirstNode like '%x%') RETURN cast(0 as bit)
   select @SecondNode = dbo.GetFirstWord(@pv)
   if (@SecondNode like '%x%') RETURN cast(0 as bit)
   -- check for count of captures
   select @shorterby = len(@pv) - ( len(replace(@pv, 'x', '')))
   -- check for count of promitions
   select @shorterby = @shorterby + (len(@pv) - len(replace(@pv, '=', '')))
   if (@shorterby <=2 AND len(@pv) >= 60) RETURN CAST(1 AS bit) 
   if (@shorterby <=1 AND len(@pv) >= 30) RETURN CAST(1 AS bit) 
   RETURN CAST(0 as bit)
end
And using it like this:

Code: Select all

SELECT 
 e.Epd + ' ' +
dbo.opcode_format('acd', acd) + 
dbo.opcode_format('am', am) + 
dbo.opcode_format('bm', bm) + 
dbo.opcode_format('c0', c0) + 
dbo.opcode_format('c2', c2) + 
dbo.opcode_format('c3', c3) + 
dbo.opcode_format('c4', c4) + 
dbo.opcode_format('c5', c5) + 
dbo.opcode_format('c6', c6) + 
dbo.opcode_format('c7', c7) + 
dbo.opcode_format('c8', c8) + 
dbo.opcode_format('c9', c9) + 
dbo.opcode_format('cce', round(coef * 444.0,0))+ 
dbo.opcode_format('ce', ce) + 
dbo.opcode_format('dm', dm) + 
dbo.opcode_format('pm', pm) + 
dbo.opcode_format('pv', pv) + 
dbo.opcode_format('white_wins', white_wins) +
dbo.opcode_format('black_wins', black_wins) +
dbo.opcode_format('draws', draws) +
dbo.opcode_format('Opening', Opening) 
,
e.Epd + ' ' +
dbo.opcode_format('am', am) + 
dbo.opcode_format('bm', bm) +
dbo.opcode_format('c1', c1) +
dbo.opcode_format('id', nid) 
,
 round(coef * 444.0,0) as oce, ce, -round((coef * 444.0 - ce),0) as distance, e.Epd, acd, pv,c3, bm, tag, e.pm, white_wins, black_wins, draws, (white_wins+black_wins+draws) as games, acs, acn, id, Opening, dm
FROM Epd e  where len(Epd) >= 37 AND games >= 200 and dbo.Quiet(pv) = Cast(1 as bit) and acd >= 45
Gives me a result set with a first column that looks like this:

Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Re: Extracting quiet positions?

I don't insist on no captures or promotions, so only one or two 'x' or '=' characters in a long pv are OK if the first or second move is not a capture.
The function looks like this:

Code: Select all

USE [Chess]
GO

/****** Object:  UserDefinedFunction [dbo].[Quiet]    Script Date: 2020-05-24 6:18:51 PM ******/
SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO


CREATE FUNCTION [dbo].[Quiet](@pv as varchar(256))
RETURNS bit 
AS 
begin 
   DECLARE @shorterby int;
   declare @FirstNode as char(16)
   declare @SecondNode as char(16)
   select @FirstNode = dbo.GetFirstWord(@pv)
   -- check for early captures
   if (@FirstNode like '%x%') RETURN cast(0 as bit)
   select @SecondNode = dbo.GetFirstWord(@pv)
   if (@SecondNode like '%x%') RETURN cast(0 as bit)
   -- check for count of captures
   select @shorterby = len(@pv) - ( len(replace(@pv, 'x', '')))
   -- check for count of promitions
   select @shorterby = @shorterby + (len(@pv) - len(replace(@pv, '=', '')))
   if (@shorterby <=2 AND len(@pv) >= 60) RETURN CAST(1 AS bit) 
   if (@shorterby <=1 AND len(@pv) >= 30) RETURN CAST(1 AS bit) 
   RETURN CAST(0 as bit)
end
And using it like this:

Code: Select all

SELECT 
 e.Epd + ' ' +
dbo.opcode_format('acd', acd) + 
dbo.opcode_format('am', am) + 
dbo.opcode_format('bm', bm) +

dbo.opcode_format('am', am) +

dbo.opcode_format('id', nid) 
,
 round(coef * 444.0,0) as oce, ce, -round((coef * 444.0 - ce),0) as distance, e.Epd, acd, pv,c3, bm, tag, e.pm, white_wins, black_wins, draws, (white_wins+black_wins+draws) as games, acs, acn, id, Opening, dm
FROM Epd e  where len(Epd) >= 37 AND games >= 200 and dbo.Quiet(pv) = Cast(1 as bit) and acd >= 45
Gives me a result set with a first column that looks like this:

This is extremely cool. Do you have any public scripts to load epds into a database? I have no SQL knowledge unfortunately.

Re: Extracting quiet positions?

Post by Dann Corbit »

I have a rather complex system for doing that.
I analyze my own positions in two categories:
1. Stockfish derivative engines
2. Non-SF engines
For Stockfish derivatives, I modify the source to log directly to disk. This is extremely reliable. I have a parser that reads the log and writes EPD records. I have a parser that reads the EPD records and writes stored procedure calls. I run the stored procedure calls using a standard SQL Server command line process.
For non-stockfish engines, I usually use Arena (but sometimes ChessAssistant or my old Shredder GUI). I have parsers that read the output of these files. Because it is not a stockfish engine, it does not log to disk as reliably, so before parsing, I run the data through a process that ensures all of the moves are legal. Also, the decoupling of the engines from the GUI happens much more frequently at high speed, so I only use slow analysis for non-sf engines. Then I run the log files combined with the original EPD files through a parser that writes decorated EPD files with the analysis from the logs. Then I parse the EPD records and create SQL files that I run through the SQL server tools.

The second category of data comes from contests run by other people like TCEC, CCRL, CEGT, etc. My friend Les Fernandez's tool CUT is used to create decorated EPD records. For every distinct contest, I have a different secondary parser because of differences in the formats and differences in the destination tables. Those parsers create stored procedure calls which I run against SQL server.

In order to process against SQL server, I have written hundreds of stored procedures and SQL functions. So all of it is necessary to correctly process the data. Much of what is written is SQL server specific and will not run against other database systems like Oracle or PostgreSQL.

Even though I have a vast array of my own machines, the greatest volume comes from external sources. I have not yet formed a procedure to convert Bojun Guo's data into analyzed SQL records, but that is on my agenda.

I guess the main problem with others trying to replicate my method is that it is both gigantic and specific. There are many dozens of different programs in use and many hundreds of stored procedures. You would definitely need the skills of a SQL Server administrator to check the database integrity, back it up and perform various scheduled maintenance tasks. I also use ultraedit to do some manual conversions. And some of my processes are finicky about line endings, so I need to convert to/from unix to windows (and on rare occasions Mac).

I don't have any manuals to explain how to perform all of the processes, it is only in my head. So I think it would be extremely difficult for someone else to do the same thing that I am doing, even if I gave them all of the code and binaries.
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Understandable and really impressive! Thank you for sharing all of that.

I'm looking for ways to extract quiet positions from an epd file while preserving existing comments, bestmove, etc., information. I have a few million positions and just need to get rid of the noisiest ones.

Are there any scripts or programs to do this? If not, does anyone have recommendations for the best way forward?

Thank you.
I have some python scripts, but what are your criteria for quiet positions? Can you post an example EPD?

From a programmer perspective, best is to perform a qsearch, if that comes back with nothing better than stand pat then the position is quiet.
You can take it a bit further and if qsearch comes back with a pv, then play the pv out until the end of the line and use that as the position

Yep, exactly this. I don't even need (or at least I don't think I need...) the part where I play out the PV until the end of the line. That idea had not occurred to me but it seems very reasonable.

If the definition of “quiet” is kept to material only, it would be relatively trivial to write a quiet-epd parser using standard stuff in Python-Chess to do the qsearch. It would be no surprise if Ferdy has already done one.
