gives a unique solution for the problem, and 
least squares adjustment is not needed. In 
this approach, error will not be easily 
identified. To obtain the redundancy that was 
available in Eq. 1, the function y, - f(xi) can 
be added to Eq. (5) and the least squares 
adjustment will be used to solve the problem. 
Also the new solution is non-linear and Eq. 
(4) can not be used.
