We address an on-line version of the visibility-based pursuit-evasion problem. We take a minimalist approach in modeling the capabilities of a pursuer robot. A point pursuer moves in an unknown, simply-connected, piecewise-smooth planar environment, and is given the task of locating any unpredictable, moving evaders that have unbounded speed. The evaders(More)

The Harvard Brain Tissue Resource Center (or The Brainbank) at the McLean Hospital is one of three federally funded centers for the collection and distribution of human brain specimens for research, and the only designated acquisition center. The Brainbank seeks to establish a publicly accessible repository (The National Brain Databank) to collect and(More)
