Planning, placement and more: Optimization makes it easier (August 13, 2007)
Many everyday decisions may be thought of as optimization problems – problems that seek to maximize or minimize desired quantities or qualities given certain constraints. Cynthia Phillips and fellow researchers consider enormously complex optimization problems and devise algorithms that let computers solve such problems quickly and efficiently.
Overture plays on methods for faster, more accurate models (July 31, 2007)
In simulating a physical phenomenon, some researchers use a single technique or algorithm. That approach is not always the best choice. Bill Henshaw, an applied mathematician at Lawrence Livermore National Laboratory, researches ways to combine computational “tools” that automatically adapt to efficiently attack specific parts of the simulation.
