Good catch! To add to your comment, I think it is a typo in the MuZero preprint. They actually fixed it in the Nature paper(page 8, right column).

Hi, @henrycharlesworth @Hwhitetooth
Really thank you for correcting the formula!
This is a mistake, and it should be h1, rather than h2.
.
Current implementation will lead to larger error. And we will correct this formula later.
More importantly, we can find that when x >= 0, h1(x) is equal to h2(x). When x < 0, we have
Since eps=0.0001, the error of h1(x) and h2(x) is small. Therefore, it probably doesn't make much difference.
And thank you again for your detailed discussion!
