Michael James David Powell FRS FAA[1] (29 July 1936 – 19 April 2015) was a British mathematician, who worked in the Department of Applied Mathematics and Theoretical Physics (DAMTP) at the University of Cambridge.[2][3][4][5][6]

Education and early life[edit]

Born in London, Powell was educated at Frensham Heights School and Eastbourne College.[1] He earned his Bachelor of Arts degree[when?] followed by a Doctor of Science (DSc) degree in 1979 at the University of Cambridge.[7]

Career and research[edit]

Powell was known for his extensive work in numerical analysis, especially nonlinear optimisation and approximation. He was a founding member of the Institute of Mathematics and its Applications and a founding Managing Editor of the Journal for Numerical Analysis.[citation needed] His mathematical contributions include quasi-Newton methods, particularly the Davidon-Fletcher-Powell formula and the Powell's Symmetric Broyden formula, augmented Lagrangian function (also called Powell-Rockafellar penalty function), sequential quadratic programming method (also called as Wilson-Han-Powell method), trust region algorithms (Powell's dog leg method), conjugate direction method (also called Powell's method), and radial basis function.[citation needed] He had been working on derivative-free optimization algorithms in recent years, the resultant algorithms including COBYLA, UOBYQA, NEWUOA, BOBYQA, and LINCOA. He was the author of numerous scientific papers[3] and of several books, most notably Approximation Theory and Methods.[8]

Awards and honours[edit]

Powell won several awards, including the George B. Dantzig Prize from the Mathematical Programming Society/Society for Industrial and Applied Mathematics (SIAM) and the Naylor Prize from the London Mathematical Society.[when?] Powell was elected a Foreign Associate of the National Academy of Sciences of the United States in 2001 and as a corresponding fellow to the Australian Academy of Science in 2007.[7][9][10][11]
