Re: Last green Net nn-62ef826d1a6d.nnue

Why is the last green NNUE already 2 months old ? After that, about 100 new networks have already appeared, but none is recommended (i.e. green). Are they all worse than nn-62ef826d1a6d.nnue ? The series of “green” nets were trained via RL (reinforcement learning) and possibly are very close to the...

Really? When was the last time a top player competed on even terms? Nakumura just lost to komodo dragon while given a pawn advantage.
Two pawns.

a0lite with hybrid nnue

I’ve combined Night Nurse 0.3 and Bad Gyal in a0lite julia. Night Nurse is running in a simple pvs with a pv hash (poor man’s TT). Its doing policy augmentation similar to leelafish, but with some more smarts around how much to boost policy. Once checkmate appears over the night nurse horizon, it te...

Re: It's NNUE era (sharing my thoughts)

I only want to say that "NNUE Era" and "Copy-Paste SF NNUE Era" are two basicaly different rhings. The first is beautiful while the second is unworthy. In many discussions here, these two concepts are not separated, which is a great mistake. The Night Nurse nets (and the Toga ones, for that matter)...

Re: Introducing Toga III chess engine

Toga III 0.2 is at 3019 on the CEGT 40/20 list. As I’ve said, 3300 is the new 3000.

Re: It's NNUE era (sharing my thoughts)

Double standards. You shall earn every +Elo with blood, sweat and tears! :lol: It’s changed the engine improvement workflow and skill sets. To develop a 3000+ engine, you had to implement a good search and a good eval, then tune them so they worked well together. With NNUE, you just can focus on se...

Re: Some beginner questions about Lc0

If your GPU is only at 15% utilization, then your cpu isn’t feeding the gpu enough. I’d try the default values and see if you can get close to 100%.

Re: Some beginner questions about Lc0

One more.I have read, that Lc0 needs a lot memory to run well. But how do You increase memory? Even if I increase hash to XX GB and NN cache to zillion system monitor says always about 2 GB GPU memory used and 15% of GPU power. System monitor sucks I quess? While the code for lc0 may be complex, yo...
