# PDFO: Powell's Derivative-Free Optimization solvers

Dedicated to late Professor M. J. D. Powell FRS (1936–2015).

We look forward to your feedback! Thank you very much!

## Getting started

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.

This package makes use of a modified version of Powell's Fortran code. See the folder original under fsrc for Powell's original code.

## Acknowledgments

The development of this package is funded by the UGC of Hong Kong (ref. PolyU 253012/17P, PolyU 153054/20P, and HKPFS PF18-24698), and The Hong Kong Polytechnic University.

PDFO is dedicated to the memory of late Professor Powell with gratitude for his inspiration and for the treasures he left to us. We are also grateful to Professor Ya-xiang Yuan for his everlasting encouragement and support.
