Thomas Neidhart resolved MATH-678.
----------------------------------
    Resolution: Incomplete

Closing as the mentioned instabilities have never been documented.

>         Environment: Java

> As per a discussion on the mailing list, I am opening this ticket. In applying the nonlinear
optimizers in commons, I noticed what I believe to be instability in the techniques. Further
investigation investigation (both of my tests) and the code in prod is warranted. 
> I will be pushing a first set of tests which should illustrate what I am seeing.
