Was the test single threaded?
Jonny could be misconfigured.
There are many other possibilities.
I don't know, it's from CCRL 40/4. Reading about Jonny
...Jonny uses a 0x88 board representation, and applies a sophisticated distributed and parallel search.
So maybe that was the problem, thanks!
Normally we would need eval/depth (which is not available for the 40/4 games) to investigate the case the best (missconfigs or cpu overloads happen...), but in this case it is extremely unlikely that Jonny 4.00 was hit 3 times by an asteroid in the last 2 or 3 months.
I am saying this, because Jonny 4.00 suffered the same extreme outlier negative result, not only vs. Tunguska,
but also vs. Topple and FranMAD. I am convinced, something went wrong here.
Code: Select all
– Topple 0.5.0 64-bit 4CPU 2845 +24 -24 (+99) 0.5 - 44.5 (+0-44=1) 1.1% 0.5/45 0.0% -590
– Francesca MAD 0.21 64-bit 2709 +20 -20 (-37) 1.5 - 37.5 (+0-36=3) 3.8% 1.5/39 100.0% -532
A fishy example game below.
(even w/o eval/depth it should be possible to analyse, if Jonny did not reach normal depth here to lose that way)
I checked a few positions after the opening and Jonny played often moves, which are already discarded here at depth 10-12
after one second...(on my slow 10 years old quadcore - 1 cpu of course), e.g. 13. Qa4?? and others.
