Re: 2 open projects

One of the big open questions for me is: AZ0 ended up 100 Elo above SF8. Did DeepMind just pull the plug when they got a good enough result (likely), or did they simply not get it higher (not impossible either). For me as well. I wonder by how much can the NN be increased before the the decrease in...

Re: 2 open projects

... Silver said in that keynote talk that they did multiple runs, and I'm pretty sure they didn't publish the results of a run where they had the sorts of bugs the Leela project has had so far :) ... Yes, it's safe to assume the 9hrs & 44m games started after they were happy it was bug-free. It wou...

Re: LC0 on the WAC test suite, bad results

If neural nets work like human neural nets, then I would expect that tactics can be learned also. A human can recognize many tactics by pattern recognition. Simple example. KR vs K, instantly recognized as a win and the algorithm for winning is also imprinted in the brain to play without even think...

Re: LCzero sacs a knight for nothing

Gee, you got it almost all wrong. Mainly because figure 2 is totally bogus. First scaling of SF is bogus. It can be easily demonstrated that SF8 on 64 cores when going from TC = 1s/move to 1min/move gains at least 40*6 = 240Elo. They show in figure 60Elo?!???! If it can be easily demonstrated then ...

Re: LCzero sacs a knight for nothing

duncan wrote:do you have an estimate for elo of alphazero ?
Since SF8 4CPU is 3386 CCRL 40/40 thus 64 core setup with ~ 2x faster cores than CCRL reference should be at least 3525+
So A0 + 4xTPU should be 100 elo above, thus 3625+ on CCRL 40/40?

Re: LCzero sacs a knight for nothing

Therefore, just a factor of 4 in time control (or hardware) (2 doublings) gives a boost of 128 Elo points compared to standard A/B engine. Or 64 Elo points per doubling. One can extrapolate: On one CPU core at 4 s/move, from this match LC0 ID160 is about 2100 CCRL Elo. A top GPU, say Nvidia 1080 Ti...

Following this guide with InBetween 1.3 has worked for me (for GPU and CPU version).

Re: LCzero sacs a knight for nothing

LC0 on GTX 1080Ti gets around 2.5knps on average. LC0 on my (old Sandybridge) 16 cores machine running on 32 threads gets 2knps on average. My GTX970 get's around 2k nps and it's 3.9 TFLOPs, while 1080Ti is 11 TFLOPs so I would expect more like 5k+ nps from 1080Ti (on current LC0 network size) Also...

Re: LCzero sacs a knight for nothing

A GTX 1080 Ti is 11 TFlops, and 64 cores is 1 TFlops so that is an 11X hardware advantage. Why not use the same 64 CPU cores for it and see if it will beat Stockfish ? You have elevated the minimum hardware requirement for A0 to be competitive with Stockfish to 11 x 64 = 700 CPU cores each thinking...

Re: LCzero sacs a knight for nothing

You mean a random FEN? Even if this is the case, compared to _positional_ "random FEN" opening suite, the results are completely opposite: I think that's no coincidence that LC0 is positionally stronger and tactically weaker to engines of comparable strength. Just try to imagine you were a self lea...
