New Lightweight N-body Algorithms

Dr. Alexander Gray

Robotics Institute at Carnegie Mellon University

Abstract:   I will present a new kind of N-body solver which can be seen as filling a conceptual gap between Barnes-Hut and the FMM. It has the flexibility of Barnes-Hut, allowing it to be applied to problems where analytic expansions are not available, as well as its simplicity, yet has the computational complexity of the FMM.
