29.1 is the first one, that doesn't work correctly with MEA (Ferdinand Mosca). Given milliseconds for each position aren't interpreted correctly, everything <500 is ignored. No error message, run is completed and rated, just the TC is wrong.
Tried already to set Move Overhead and Slow Mover to minimum, doesn't help neither.
Best regards

ShashChess 29 uses the win probability to classify positions based on Shashin theory and uses for this the formula in Stockfish wdl model. This formula is rather computationally onerous.
Therefore, in ShashChess 29.1, we introduced a hashmap (to be precise, unordered_map), initialized at engine startup in a similar way to syzygy, so that we have immediate access to the win probability, given a score and depth of analysis.
I am trying to figure out how this might impact this tool that I am not familiar with.

Re: ShashChess
Thanks for explaining and looking into it, Andrea, just to notice again, with version 29 the TC was interpreted correctly still, 29.1 is the first one aberrant as for the tool and its fixed time per move syntax, regards
Peter.

BTW, as for Banksia 0.58 positional test tool it's about the same, 200 msec/pos. given takes about 8.5 min for 512, that's well 5 times too much:

>750 msec TC- interpretation starts coming nearer to the one of other engines, but yet even with 1"/move, there's still about 150% time consumption by ShashChess 29.1 than by other engines in GUIs that allow so (and in console like with MEA).peter wrote: ↑Wed Mar 08, 2023 7:44 pm BTW, as for Banksia 0.58 positional test tool it's about the same, 200 msec/pos. given takes about 8.5 min for 512, that's well 5 times too much:

In my test 29.1 + Tal is very good in testsuites! But Crystal 5 is even better in all suites.

Re: ShashChess
5" is the shortest TC 29.1 at least in Fritz GUI interpretes correctly,
at 1" even in Fritz (18) 578" instead of 512 max given are used yet still:
EloStatTS relativizes the time to solution additionally anyhow.. For 5"/postion and 30 threads of the 16x3.5 GHz- CPU I like e.g. these 256:Ergebnis: 443 aus 512 = 86.5%. Durchschnittszeit = 0.72s / 9.38

Re: ShashChess
As for MEA, TC given 100msec/pos. for ShashChess 29.1 results in about same time consumption (with Move Overhead and Slow Mover set to min.) like with other engines default setting and 750msec/move (like e.g with ShCh 29 too), all engines execpt LC0 (Nividia 3070ti GPU) ran with single thread of 3.5GHz CPU over these 2345 positionspeter wrote: ↑Thu Mar 09, 2023 10:28 am >750 msec TC- interpretation starts coming nearer to the one of other engines, but yet even with 1"/move, there's still about 150% time consumption by ShashChess 29.1 than by other engines in GUIs that allow so (and in console like with MEA).
