Hello SPAMS enthusiasts,

Tomorrow in SPAMS we have Alex Dubbs, who will be speaking on a clever technique
for high-dimensional integration.

I was informed an alternate version of the title was "QMC and Sparse-Grid
Integration." For the unfamiliar reader, we provide a list of top google hits
for "QMC" right here:
 - Quartermaster Corps
 - Quinto Mining Corporation
 - QMC(SW) Husted's Goat Locker
 - Quasi Monte Carlo

Which one is real, come tomorrow and find out!  (But a word of warning to those
with allergies to goats).

Title:  High-Dimensional Quadrature on Sparse Grids

Abstract:  This talk explains Sparse Grid Quadrature, a technique for
numerically integrating a function of many variables.  I compare it to the two
"extremes" of tensor-product integration (which is dimensionally cursed) and
pure Monte-Carlo integration (which is slow-converging), and give theoretical
intuition into why it operates in the middle ground.  Performance analysis is
done on a few test integrands.  Additionally, beautiful pictures of quadrature
grids are shown.
