image Hello and thank you for your excellent work. Here is a puzzling question that I would like to have answered by you. In lines 3-4 of Algorithm 1, I can't figure out if there is any difference between z0 in the third line and z in the fourth line.The transformation in lines 3 to 4 doesn't seem to have any additional loss and each of the term's is deterministic. Also, what is the output z of the algorithm? I instinctively feel that the process of inversion is z0 to zT (noise), but it seems that this output z is still z0?

Also confused about Algorithm 1.

The algorithm 1 is intuitively meaningless, and it’s just a reference for algorithm 2. So if you are confused, feel free to ignore it.
