"Stalking the Wild Integral",
I gave a talk , to the
"Science for Lunch Bunch" (free pizza)
at the Pittsburgh Supercomputing Center, on 27 June 2007.
I also presented this talk to the MATH 2070 -
Numerical Methods in Scientific Computing class,
at the University of Pittsburgh,
23 November 2009.
A plain text abstract of the talk is available as
sparse_2007_psc.txt.
