How to optimize the number of anchor points in a vector image?

Question

Vector editor

Good evening!
Some time ago, I asked myself a question: reducing the anchor points, while the image should not visually change. I have read quite a lot of material on this subject. In particular, I liked the article - Several ways to simplify paths in Illustrator . But all the methods that I found on the Internet still visually changed the image, even the VectorScribe plugin.
Therefore, the question arose, how to optimize the number of control points in a vector image, without visual changes?
