> Hi everyone, I am very glad to announce [PRIMA](http://libprima.net), a package for solving general nonlinear optimization problems without using derivatives. PRIMA provides the reference implementation for [M.J.D. Powell](https://en.wikipedia.org/wiki/Michael_J._D._Powell)’s renowned derivative-free optimization methods, i.e., COBYLA, UOBYQA, NEWUOA, BOBYQA, and LINCOA. The “P” in the name stands for [Powell](https://www.zhangzk.net/powell.html), and “RIMA” is an acronym for “Reference Implementation with Modernization and Amelioration”. Powell’s solvers are widely used by engineers and scientists. For in…
