I don't see it listed with the help command. What is the actual
command for batched rollouts?
There is now a batch analyse function in the graphical version
of gnubg (actually also in the text) that you mind find useful.

Thanks Ian. I
run these batches overnight, but it won't hurt to add 'set
priority to idle'. I am running an i7 processor, so I'll
also add 'set threads to 4'. The whole point of this
exercise is that I ran across a ton of match files from
15-20 years ago and I'm interested in the difference in
analysis over the years. I even located my copy of Snowie4.

Hi Chris,
I think Jim is recommending that you have a copy of
.gnubg/gnubgautorc.rc with your preferred settings for batch
analysis.
In the batch file, before running gnubg, you can have
rename .gnubg/gnubgautorc.rc .gnubg/gnubgautorc.rc.play and
rename .gnubg/gnubgautorc.rc.batch .gnubg/gnubgautorc.rc.
run gnubg bg with commands
Then do the reverse at the end of the batch file to restore
the original settings.
I don’t see much difference between doing that and loading a
command file within gnubg. I suppose the main point is to,
whichever way you do it, restore the settings that you use
when not doing batch analysis, if they are different to your
regular settings.
Set threads n is the command to use to specify a number of
threads. You’d have to look up the number of cores your
processor has, and double it if you have a multithreading
processor like an i7.
I’d do it differently though. I’d use set priority low or
set priority idle. This would let gnubg use all the power
when nothing else is happening, but back off on hogging
resources when you’re doing other stuff. I have set priority
idle as a permanent setting.
Cheers,
Ian

Thanks to everyone for the information. Ok, I put the
following lines into a file called matches01.txt:
---

set analysis luckanalysis prune on
import mat 'G:\NewMatches\scoper10.mat'
analyze match
save match 'G:\NewMatches\Analyzed\scoper10.sgf'
relational add match
---
I then executed the command gnubg-cli.exe -c matches01.txt
and I received an 'Invalid argument' error. (I'm on Windows
10) I removed the quotes from around the paths and the error
went away. (The quotes were a requirement 15 years ago)
With respect to the "set analysis" parameters, are you
saying to place them into a separate file and then issue a
"load commands <parameters file>" from within the
script?
BTW, what do I issue to set the threads to half the cores?

On Windows the equivalent of gnubg -t is gnubg-cli.exe and
the -c option
works juste the same :
%homepath%\AppData\Local\gnubg\gnubg-cli.exe -c cmdfile.cmd
or something similar.

The gnubgautorc file is huge and full of irrelevant
parameters. It would
probably be simpler to start the analysis command files with
a "load
commands <parameters file>", the parameters file
containing the kind of
commands Chris shows at the beginnig of his script.
FWIW, for 4 ply analysis I use:
set cube use on
set analysis movefilter 1 0 4 12 0.32
set analysis movefilter 2 0 4 12 0.32
set analysis movefilter 2 1 -1 0 0
set analysis movefilter 3 0 4 12 0.32
set analysis movefilter 3 1 -1 0 0
set analysis movefilter 3 2 0 4 0.08
set analysis movefilter 4 0 4 12 0.32
set analysis movefilter 4 1 -1 0 0
set analysis movefilter 4 2 0 4 0.08
set analysis movefilter 4 3 -1 0 0
set analysis cubedecision eval plies 4
set analysis chequerplay eval plies 4
set analysis luckanalysis plies 2
set analysis luckanalysis prune on

reduced is not used any more but everything else should
still work.
Maybe set cache larger since current computers have plenty
of memory, or
rely on the default value set from the GUI. Maybe set
threads to some
value lower than the number of cores of your machine (half
of them ?) if
you run that while doing something else.

"Automating rollouts on a match" is tricky. There are
commands to mark
moves or cube decsions to be rolled out later. That's fine
from the GUI
or to roll out a list of positions with command files like:
set matchid cAm1ABAAGAAA
set board f/sAACDsdgsKAA
hint
cmark move set rollout 1 2
analyse rollout move
save position pos.sgf
or
set matchid cAmgABAAGAAA
set board //YAAEDtthsAAA
hint
cmark cube set rollout
analyse rollout cube
export position text pos.txt
But there is no easy way to select them automatically in a
whole match.
A way to do this would be to analyse it at, say, 3 ply, and
have commands
like:
cmark move set rollout analysed plies 3
cmark cube set rollout analysed plies 3
analyze rollout match
to roll out the errors and the decisions close enough for
the move
filters to select them for 3 ply analysis.
alas, the first two don't exist... It may be possible to do
this with
the python interface, or to add the above commands to gnubg.
