RubiChess with old net?

[Werner]

The net included in the download version RubiChess-20240112 is from August 2023 - so no new network included?

[Modern Times]

I didn't check the net other than to note that there was one. I'll check which one it is when I access my machine again. But I got +24 Elo out of it anyway.

Thanks, we just got the answer from Andreas: correct - no new network!

[Damir]

Yes when I downloaded RubiChess on my machine, it asked me if I wanted to replace the old network with new one, same name and same seize...

Andreas what is optimal Time Usage for RubiChess. I used Default 100 and lost on time after only 70 moves in draw position.

Shall I raise Move Overhead to 500 or 1000 like Stockfish does ?

Hi Damir,

what the RubiChess programmers are doing is very nice:
https://github.com/Matthies/NN

I also saw this and check and second the NN site.
I can't see any newer NN file.

Often I also look here for my opening analyses.
RubiChess is one of my TOP-10 engines for opening analyses.

Logically, the programmer can give the best answer.
Have fun with RubiChess!

Best
Frank

The problem is not about time usage of RubiChess, it is (usually) about the GUI stealing time from the engines.
Arena and ChessGUI are known for stealing a lot of time (and even Fritz? There was some report about a commercial GUI with this problem but I don't remember exactly) like 500ms or even more while others like Cutechess(-cli) limit this move overhead to < 10ms.

Rubi measures the overhead of the GUI and warns if this measured overhead is near or even exceeds the value of the Move Overhead option:

Code: Select all

            
            if (measuredOverhead > moveOverhead / 2)
            {
                if (measuredOverhead > moveOverhead)
                    guiCom << "info string Measured GUI overhead is " + to_string(measuredOverhead) + "ms and time forfeits are very likely. Please increase Move_Overhead option!\n";
                else
                    guiCom << "info string Measured GUI overhead is " + to_string(measuredOverhead) + "ms (> 50% of allowed via Move_Overhead option).\n";
            }

So you should look for messages like this in your UCI log and set the Move Overhead option to a value matching your GUI.
