Re: Chess.com 2018 computer chess championship

Also, seldepth=3. Max tree size is <= 256^3. Its not a ponder bug, its a hardware issue. Andrew, May I quote you from CCCC chat? A handful of engines (5) are randomly locked out of thread access, causing their trivial depth 1 searches to take well over a second, when usually they are < 1 micro seco...

Re: Chess.com 2018 computer chess championship

In my programming experience, the problem I had with my software were rarely hardware or compiler bug, lot of time they were software bug created by myself. Okay. This is not such an example. This was expected by everyone in this thread. No one listened. Unless you think that 5 engines all display ...

Re: Chess.com 2018 computer chess championship

Maybe the rules can be changed for the second stage and stop this ponder on hyperthreads madness. It's not like the top 8 would be any different without ponder anyways, or maybe 1 engine out of 8. I hope so. Dropping pondering will fix things, and be completely elo neutral. Dropping hyper threads w...

Re: Chess.com 2018 computer chess championship

https://pastebin.com/raw/FxRnwhHF Ethereal, Senpai, Nemorino, Shredder, Nirvanachess are shown to exhibit the same behavior ... Random depth 1 searches taking thousand of times longer than they should. Most interesting, is that games are hit or miss. There are a handful of cases where it happens to ...

Re: Official Release of Ethereal 11.00

the time-management is not perfect. Ethereal uses too much time in early midgame, when playing with small increment (compared to the base-time) (I play with 3'+1'' (=180:1)) - often all base-time is gone at move 40-45... I have no issues with the current TM. Ethereal will alloc large chunks of time...

Re: Official Release of Ethereal 11.00

Thanks Andrew, Good job! Is this more or less the TCEC version? More results for 10.97 on Sunday. Good luck 11.00 has two elo gaining patches from 10.97, one of which appears to be worth 6 elo (SPRT testing though, so it could be anything). I'de say the gains are respectable, but not enough to guar...
