The class of \u0022semi-algebraic\u0022 sets and functions -\nthose arising from polynomial inequalities - nicely exemplifies \nnonsmoothness in practice. Semi-algebraic sets (and their\ngeneralizations) are common, easy to recognize, and richly structured, \nsupporting powerful variational properties. In particular I will discuss\na generic property of such sets - partial smoothness - and its \nrelationship with a proximal algorithm for nonsmooth composite\nminimization, a versatile model for practical optimization.\n\u003Cbr \/\u003E\n\u003Cbr \/\u003EBio:\n\u003Cbr \/\u003E\nAdrian S. Lewis was born in England in 1962. He is a Professor at \nCornell University in the School of Operations Research and Industrial \nEngineering. Following his B.A., M.A., and Ph.D. degrees from Cambridge, \nand Research Fellowships at Queens\u0027 College, Cambridge and Dalhousie \nUniversity, Canada, he worked in Canada at the University of Waterloo \n(1989-2001) and Simon Fraser University (2001-2004). He is an Associate \nEditor of the SIAM Journal on Optimization, Mathematics of Operations \nResearch, and the SIAM\/MPS Book Series on Optimization, and is a \nCo-Editor for Mathematical Programming. He received the 1995 Aisenstadt \nPrize, from the Canadian Centre de Recherches Mathematiques, the 2003 \nLagrange Prize for Continuous Optimization from SIAM and the \nMathematical Programming Society, and an Outstanding Paper Award from \nSIAM in 2005.
