Question of the Table 3~5

[Antimaths]

@huangwl18 @pathak22
I was trying to reproduce the Table 3~5.
e.g. , for the first picture in Table 3, I have confused about what the Y axis means (Mean Rewards)?
Because I find in your main.py , we can draw the tables for every Walkers(10) ,but there is no table for the Mean Rewards.
So am I missing something ? Or can I have your codes for the Mean Rewards ?
Thanks very much!!
