@chrisdavis2161 Жыл бұрын

@@dannygjk In the search function, a line of code that handles the static eval initialized to zero, when its value was actually 32000. I'm no coding expert, nor am I an expert in Stockfish coding. Using pure logic, I think this made SF think complex positions were more equal than they really were. Not a huge problem with lower rated engines, but not ideal for an engine very close in its playing strength. What made things worse imo is that the default neural net was trained with the bug in place.

@@chrisdavis2161 What do you mean, that it was supposed to be initialized to 32000 instead of 0?

@lockaltube Жыл бұрын

@@dannygjk I suppose the fix is "Stockfish/pull/4309" (google this), a problem that could be caught with clang-tidy, for example. Also last week stockfish devs added "-Wconditional-uninitialized", I guess because of this problem. Anyway, the lesson learned, it is nice to remember that there are people behind all these engines and these competitions are between developers, not machines.

Afaik there has been a few breakthroughs for Lc0 recently, so it closed the gap a tiny bit. But the fun thing is, SF is trained on Lc0 data, thus if Lc0 improves, SF automatically improves too, tho perhaps not by the same amount.

@kohlerm113 Жыл бұрын

This is an early version of LC0 running on a "transformer network" architecture, similar to what GPT-3 is based on. It is currently even slower than than the "old" lc0, but gained already significantly in strength.

@kikiraindeer7782 Жыл бұрын

wait i think the opening messed up stockfish...i believe stockfish had it

@pukulu Жыл бұрын

Stockfish has dominated LC0 for a few years but it's because stockfish can maneuver tirelessly with a space advantage until the opponent misses a deep tactical idea. LC0 is not as good at that kind of struggle. In positional and strategic struggles, LC0 is the equal of stockfish, and they are not identical, so LC0 can still win a crucial game once in awhile.

@@soumyaroy5455 I have no idea but it's doing fairly well as it is. I hope that its programmers don't become discouraged when it loses a match to stockfish. After all, Leela is stronger than every other chess program out there, including KomodoDragon, which is also very strong.

LCzero first 1-2 movies as a white were a waste of movies, it looked confused in every game. It looked it takes couple of movies to asset situation and only than start playing. She just wastes initiative as a white. I was wondering is it a bug or it is just slower. Did not watched last tournament.

It was the cup so only 16 round not 100 round like the super final I am sure if you cut the super final anywhere and took only 16 round you could find sequence where Leela was ahead.

@yanceyward3689 Жыл бұрын

This is probably not true for the last several superfinals in which Stockfish prevailed- Stockfish rarely lost in opening matchups against Leela. The rounds were either drawn with each winning the "good" side of the opening and losing the bad side, or the engines drew both sides. When there was a decisive result, it was the Fish winning a game, or both, and Leela not winning a game or only one. You could probably put together 16 rounds where the two drew 15 and Leela won a single round.

@@Jozarovschesschannel usually tests for strength are done using much faster time control, much weaker hardware and much more games, but importantly the elo uncertainty is kept low. It is not feasible to run many games with such good hardware and long time control, thus these events are geared more towards entertainment. The normal TCEC event does have the 100 game format, but honestly that is still SSS.

@dannygjk Жыл бұрын

Even 100 is a small sample size. The crucial factor is the opening lines chosen for the match.
