After each iteration I calculate a point, as average for two points received by different ways (a "counter-clockwise" way and a "clockwise" way, on half of quantity of points of a polygon everyone)

But amount of points are less than 10. It causes fears. Is it weak convergence?

In what way I can choose a good point for initial approach of a starting point?
