I thought it might be interesting if this algorithm I made could be
incorporated somehow into the free select tool, it is a way to infer a

How do you define "smooth"? With B├ęzier splines, it means that the tangents at the anchors points are collinear. By construction, your algorithm makes them not so, and it just strives to reduce the angle by multiple iterations. Do you have an estimation of how many iterations you need before the angles are no longer visible?
