Hi,

First, please use a [math] marker when using this list for questions
regarding commons-math. The list is shared among all commons components
and this policy helps filtering the messages.

Algorithms are added to commons-math as need arise, progressively. So if
you need a quasi-newton the best way is to raise an issue in JIRA
<https://issues.apache.org/jira/browse/MATH>. I guess the BFGS method
would be a good first candidate as a quasi-Newton.
