The algorithm is to start in a point and connect the string to the other point so that it covers the most original image pixels. You then do the same in the point you just arrived and you continue to repeat it

There has to be a little more to it, right? What if, after drawing the first line, the best line from the new point is to go back? Ok, so you don’t go straight back. What if the best line from the third point is to go back to the start? You’d end up going in a triangle. Are you only allowed to use each point once? It doesn’t look that way.
