Hi Ichikawa san,
Thank you for nice explanation. I think your guess is maybe right.
And 2018 nature paper might have no mistake.
I had checked carefully both Figure 1.
1. 2017 reaches AlphaGo Lee in 170,000 step. 2018 reaches in 80,000 step.
2. 2017 and 2018 reach "AlphaGo Zero(20 block)" in si
Yamashita san,
About your question, I think that the answer is yes.
AlphaZero Symmetries seems successfully saturated.
That means that 20b neural network with symmetries has a capacity to learn at
most 21M full games.
If you let the network to learn 21M full games without preprocessing inputs fo
