Rustic Alpha 1 has just been released. Congratulations for a first fully functional engine - I played a game against Rustic and got checkmated, so it works :) (I'm a very weak player and I blundered a lot). So it seems I can no longer tease you for not having written an engine :) This is just the b...

Now, of course, I think people should write their own code, or use code with permission. But it seems like we don't even want people to learn from each other. I think you possibly misunderstand what this is. The author has effectively copy-pasted Stockfish's evaluation function into their engine (t...

thanks, Werner.
good result for Cheng (better than what I expected), so even if it goes down a bit with more games, I'm glad it holds even at longer TC

No difference in terms of nodes count (or any other statistic Minic is able to print), so no obvious bug.
But 10% lower nps.

10% lower nps - that's at most 10 elo at hyperbullet, realistically about 5.
so I wonder where you get -45 I suspect an issue with testing.

P.S. Martin, comewhere in the Cheng thread you've mentioned something like: "because I've made no progress since 4.40dev and because CEGT is already testing Guenther's compiles" - I just wanted to ask what you do when feel that kind of reaching the limits - when you feel like you can't make an engi...

I see. I would be more than happy with 30+

I see. have you tried to mask it to 32 bits (or 31) first, like hashKey &= 0xffffffff? then use %?
still - if you round number of entries to nearest power of two and then mask with num_entries-1, it should work as is

I don't understand your masking around hashEntries: var hashEntry = hashTable[hashKey & (hashEntries - 4)]; why -4, plus hashEntries seems nowehere close to a power of two (default is some weird value like 16M/80, so I'm puzzled if hashEntries was 2**n, then masking with (hashEntries-1) I would unde...

thanks for the tournament, it was fun to follow except for some hiccups (like streaming stopped after n rounds for some reason etc.)

thanks for testing Cheng (Gabor I guess?)
if this result holds, that would mean that I broke 3k CCRL blitz - a very important milestone to me (even if elo is relative)
