Small bug (I think):
If you have overridden engines' options for threads and hash in a tournament, when you hover over the engine's name during a tournament game, in the status bar it shows the cores/hash from the engine's settings, instead of the cores/hash used right now.

gauntlet

3 engines selected
I should get 400 games
Engine 1 vs Engine 2 100 openings reversed sides = 200
Engine 1 vs Engine 3 100 openings reversed sides = 200
but it says only 200 games will be played.

Re: Myracle GUI
Question for the GUI author. Is it possible to remove or make these three tabs invisible?

Re: Myracle GUI
Hello Martin,
many thanks for this cool GUI, I realy like this clean look!
I have one question: is it possible to add the solving times and the average solving time when running an epd test suite? This would be an important feature.
Thank you!
regards
William

If you keep bothering here, Martin will probably add a fourth tab specifically for you.Krzysztof Grzelak wrote: ↑Sun Jun 07, 2026 8:17 am Question for the GUI author. Is it possible to remove or make these three tabs invisible?

Re: Myracle GUI
repeat reverse is the right checkbox to tick, repeat openings means all engines will use the same opening each round, this is not the first time it causes a confusionModern Times wrote: ↑Sun Jun 07, 2026 7:17 amIt doesn't seem to be this:Modern Times wrote: ↑Sun Jun 07, 2026 2:03 am Quick question.

the repeat reverse doesn't add new games, it simply forces to repeat the same opening with reversed colors each other cycle, it works a bit different from cutechess, there's no games per encounter
so in your case, assuming a gauntlet: you have 1 seed and 2 opponents, each cycle the seed plays 2 opponents,
so after 100 cycles you get 200 games
if you want 400 games you have to double the cycles to 200 in this case; the setup always shows the number of games and rounds
to be played to make it easier

Re: Myracle GUI
Thanks, I will try this 
Presumably as with Cutechess, there is the chance that the same opening may be randomly selected more than once during a tournament ? With a large enough book or pgn that becomes less likely though.

Re: Myracle GUI
if the pgn contains more lines than scheduled games, this shouldn't happen (unless you add/remove engines on the fly which forces new opening set to be generated)Modern Times wrote: ↑Sun Jun 07, 2026 12:10 pm Thanks, I will try this

the way I do it is I load all the pgn games into memory first, then shuffle all of them (the indices actually)
and then I simply walk sequentially on the shuffled indices and pull them - so assuming this works as intended,
you should never see the same line except for the reverse, assuming repeat reverse is checked
EDIT: of course if the pgn contains the same line multiple times (within max ply if enabled), the of course it may repeat
