Optimal Design of Groundwater Remediation Systems with Sampling Methods

Date : January 25, 2006 (Wednesday)

Time : 5:30 p.m. - 6:30 p.m.

Venue : Room 513, William M.W. Mong Engineering Building

(Engineering Building Complex Phase 2), CUHK

In this talk we discuss a class of problems in optimal design of subsurface
remediation and flow control systems. The objective functions and constraints
are constructed from PDE solvers for the flow and species transport equations.
We show how to realize the problems with well-known production codes, how
these codes and the underlying physics present obstacles to the optimization
algorithms, and how sampling methods, in particular implicit filtering, can
overcome these problems.

The objective functions and constraints in these problems are typically non-
smooth in all the design parameters and discontinuous in some of them. We will
discuss the physical reasons for these properties and how optimization methods
can deal with them.

C. T. (Tim) Kelley has been working in numerical methods for optimization and
nonlinear equations for over 25 years. After graduating from Purdue
University, he was a postdoctoral associate at the US Army Mathematics
Research Center in Madison, Wisconsin for a year. He then moved to the
Mathematics Department at North Carolina State University, where he is now
Drexel Professor of Mathematics. He is the author of three books, over 100
papers, and has supervised 14 PhD students. He is currently serving on several
editorial boards, and is the Vice President for publications of SIAM.
