how to set the parameter to run elf_opengo at same playout / visits of leelazero

[l1t1]

I use command line

D:\tool\go_gui\gogui-twogtp -black "D:\elfv2\play_opengo_v2\elf_gpu\df_console.exe --load d:/elfv2.bin --mcts_rollout_per_thread 80" -white "D:\leela-zero-0.16-win64\leelaz.exe --gtp -w D:\elfv2.gz --noponder -v 1601"  -games 10 -sgffile fbg_lzelfv2 -auto -komi 7.5

elf_opengo memory 1308780k avg cpu usage 5%
leelaz memory 455112k avg cpu usage 25%
my gpu NVIDIA GT 730
my cpu intel i5 6600 3.3Ghz

seems your are using --mcts_rollout_per_thread 80

Try to change to 800. Also switch B and W to get an unbiased estimate

800 is too slow, and result isnt good
