PDFO (Powell's Derivative-Free Optimization solvers) is a cross-platform package
providing interfaces for using late Professor M. J. D. Powell's derivative-free
optimization solvers, including UOBYQA, NEWUOA, BOBYQA, LINCOA, and COBYLA.
See https://www.pdfo.net for more information.

To use the MATLAB version of PDFO, see README_mat.txt.
