Unless they've changed a lot of things since the original paper, this is a bit exaggerated.
MuZero learns what moves are allowed in a given position/situation, but it still needs to know a finite overall set of possible actions.
E.g. for chess, it isn't told which fourty moves a available at each point in its search tree, but it still knows to only consider 64x64 discrete options.
- tromp 6y ago> only consider 64x64 discrete options It wouldn't know that moving its King from e1 to g1 must be accompanied by moving its rook from h1 to f1. Or that moving a white pawn from e5 to d6 must in some cases be accompanied by removing the black pawn on e6. I guess the environment does these in response. That doesn't suffice for moving its pawn from b7 to b8 must be accompanied by replacing said pawn by some other piece.
