** Infeasible solution. Convergence too slow. The change in objective
has been less than 1.1931E-08 for 20 consecutive iterations.
** Warning ** The variance of the derivatives in the final
point is large (= 4.2 ). A better scaling or
better bounds on the variables will probably
help the optimization.
