The match LC0 173_101eeb41 N128k against Stockfish 130418 D15 should be finished soon, I hope, but I started a new one two days ago.

If we take two versions of LCZero, between which a month of development:

Code: Select all

173 	101eeb41 	5176.54 	50526 	10 	128 	2018-04-23 01:43:00.201447 -0400 EDT
330 	de60388a 	5905.68 	68274 	15 	192 	2018-05-23 09:43:14.535737 -0400 EDT
we can see about 200 elo increase against Stockfish 130418 D15:

Code: Select all

   # PLAYER                   :  RATING  ERROR  POINTS  PLAYED   (%)
   1 Stockfish 130418 D15     :   431.6   69.3   342.5     400    86
   2 LC0 330_de60388a N714    :   194.3   78.2    41.5     200    21
   3 LC0 173_101eeb41 N2k     :     0.0   ----    16.0     200     8

White advantage = 39.03 +/- 19.63
Draw rate (equal opponents) = 50.00 % +/- 0.00
We can assume that LC0 173_101eeb41 N256k would have about the same strength as Stockfish 130418 D15:

Code: Select all

   # PLAYER                    :  RATING  ERROR  POINTS  PLAYED   (%)
   1 Stockfish 130418 D15      :   113.3   34.6   237.0     385    62
   2 LC0 173_101eeb41 N128k    :    60.8   51.2    79.0     185    43
   3 LC0 173_101eeb41 N64k     :     0.0   ----    69.0     200    35

White advantage = 32.51 +/- 14.00
Draw rate (equal opponents) = 50.00 % +/- 0.00
Therefore LC0 330_de60388a with 91429 playouts per move should be about 200 elo stronger than Stockfish 130418 D15.

91 429 playouts for 192x15 LCZero is about 256 000 playouts for 128x10 LCZero:

Code: Select all

    4,000      1,429
    8,000      2,857
   16,000      5,714
   32,000     11,429

  128,000     45,714
  256,000     91,429
  512,000    182,857
1,024,000    365,714
The new match is LC0 330_de60388a with 91429 playouts vs. Stockfish 130418 D15.

91 429 playouts for 192x15 LCZero is about 256 000 playouts for 128x10 LCZero:
So basically it is roughly 2 minutes per move if you use cudnn version of LC0 on 1060 vs. 50ms it takes SF to reach depth 15 on something like 4 cores.
2500x advantage in time for 200 Elo advantage. Lc0 seems to really reached SF in strength :lol: :lol: :lol:.
