## The Steiner ratio conjecture for cocircular points.(English)Zbl 0774.05031

The authors show that the Steiner ratio conjecture holds for $$n$$ points on a circle.
The reader should notice that in between a complete proof of the Steiner ratio conjecture has been given by D.-Z. Du and F. K. Hwang [Algorithmica 7, No. 2/3, 121-135 (1992; see the review above)].
