** Warning **  The variance of the derivatives in the initial

point is large (= 5.1 ). A better initial

point, a better scaling, or better bounds on the

variables will probably help the optimization.

** An equation in the pre-triangular part of the model cannot

be solved because the critical variable is at a bound.
