Re: Possible "real" hash collision

Maybe just try not testing for 3 on PV nodes, only at the root.

Re: Possible "real" hash collision

It might not be an issue in this case, but something that many engines (including Tinker) are surprisingly sensitive to is how to handle repetitions. I have found that the full 3-reps test should be used at the root, but anywhere in the search to score the 2nd rep as a draw and not to wait for the 3...

Re: Wb2uci adaptor

I understand your frustration. My point was that I suspect that the custom GUI is the issue. If you implement bare-bones UCI support and output per the UCI spec, the CCC GUI should be able to deal with it. Cutechess-cli is not the issue, of course. BTW, IIRC the Leela devs in the early days were som...

Re: Wb2uci adaptor

I might well be mistaken, but I seem to think the CCCC (is it 3 or 4 C's?) event GUI is a custom one, so even if it uses cutechess-cli, there may be UCI-only issues. While I personally prefer CECP for the control it affords to the engine, I eventually just added minimal UCI support to Tinker (not th...

Re: Question on current LC0 development

The 4xxxx series is the main line of nets. The 5xxxx series is for testing changes on smaller nets that can be trained and evaluated in test matches much faster as they are smaller (although able to hold less information). See:

Re: Sapeli 1.0 - New chess engine

Some would say reporting the score from white's point of view is a feature, not a bug. Of course, many GUIs can handle this as an engine-specific option, provided people are aware of it when setting up the engine. PS I happen to not like the white POV approach myself because the vast majority of eng...

Re: SSD Problem

Thanks for the info. I have been booting back and forth for many months with no problems. I did find the Easeus recovery tool and ran another recovery tool also (MiniTool Power Data Recovery). There are between roughly 13 and 39 million files on the drive (depending on the tool). I don't actually ne...

SSD Problem

A setback. Looking for a good disk recovery utility. My 1TB SSD had 300+ GB free, but WinRAR and tar could not expand anything saying it was full. This was under both Win7 and Ubuntu. The disk was Win7 NTFS. It was strange. Got the notion that Win7 disk defrag might help. It ran for 3 days... Things...

Re: EVGA GeForce GTX 950 2 GB

I know next to nothing about laptop video cards. That said, personally, I would never run Leela for any long time on a laptop at all. For desktop gpus, I would not bother with any over-clocking or "free" bundled games. The question is the number of fans or the sealed one with just the one fan (these...
