PRIMA is a package for solving general nonlinear optimization problems without using derivatives. It provides the reference implementation for Powell's derivative-free optimization methods, i.e., COBYLA, UOBYQA, NEWUOA, BOBYQA, and LINCOA. PRIMA means Reference Implementation for Powell's methods with Modernization and Amelioration, P for Powell.
With the binding / implementation of PRIMA in C, Python, Julia, and MATLAB all being worked on, the only major scientific-computing-oriented language missing from the list is R.
