Life

Powell earned a bachelor's degree as well as a doctorate (D. Sc.) In 1979 from Cambridge University . Here he was also a professor.

He worked in the field of numerical mathematics , especially mathematical optimization and approximation as well as radial basis functions . His contribution to quasi-Newton methods is reflected in the name Davidon-Fletcher-Powell algorithm (with William Davidon , Roger Fletcher ).

In his final years he had worked on derivative-free optimization algorithms, including UOBYQA, NEWUOA, BOBYQA, and LINCOA, which are included in PDFO (Powell's Derivative-Optimization solvers) with MATLAB and Python interfaces.

In 1982 he received the George B. Dantzig Prize of the Mathematical Optimization Society and in 1983 the Naylor Prize of the London Mathematical Society , which in 1999 also awarded him the Senior Whitehead Prize . In 2007 the Catherine Richards Prize from the Institute of Mathematics and its Applications was added.

He was a corresponding member of the Australian Academy of Science and the National Academy of Sciences , a member of the Royal Society and a Fellow of the Institute of Mathematics and its Applications .

He was editor of the Journal for Numerical Analysis.
