Tool that outputs average search depth

[Joerg Oster]

I know that the 'Little Blitzer GUI' automatically does this, but I run Linux on my PC and play the games with cutechess-cli.
Is there a tool that outputs the average search depth for each engine from games in a pgn? Would be really helpful.

I maintain it myself and store it in a txt-file.

Example

Code: Select all

ENG1   72:01:43 (523.426M nodes) NPS = 2.019K
ENG2   71:59:50 (516.386M nodes) NPS = 1.992K

Depth Stats       MIDG   END0   END1   END2
ENG1             11.68  12.14  12.91  16.17
ENG2             11.57  12.08  12.87  16.16

The Fritz GUI does output the average search depth for engine matches.
But since it is an average including beginning (book => depth 0) and endgame (depths can go very high, and if tablebases GUI are used, depth=0) that average has to be viewed with caution.

Here is a PGN output:

I've written a little parser that takes a pgn and builds the average search depth for moves in mid game positions (about move 10 - 25)

But it requires Windows.

How does one use that?

Hi Thomas,

this looks great.
Would you mind sharing it so I could give it a try under Linux via wine?

Hi Ernest,

I know the Fritz-GUI, of course.
But since I don't (want to!) run Windows any longer, this is a no go.

Thanks, Jörg.

Hi,

I uploaded it to my website.

http://www.fam-petzke.de/downloads/pgn-parser.zip

I also included the source code for anyone interested to make a native LINUX compile.

The package contains 2 executables

parser.exe takes up to 10 pgn files as input paramter and builds the average midgame search depth found in them

pgntest.exe takes 1 pgn file but collects the search depths separate by engine. It takes the first two engines it finds in the file.

pgntest.exe works excellent via wine. Many thanks!

Jörg
