Following the decontamination metaphor for searching a graph, we introduce a cleaning process, which is related to both the chip-firing game and edge searching. Brushes (instead o...

This case study in UbiComp technology and design presents a "Playful Toothbrush" system for assisting parents and teachers to motivate kindergarten children to learn pro...
In the recently introduced model for cleaning a graph with brushes, we use a degree-greedy algorithm to clean a random d-regular graph on n vertices (with dn even). We then use a d...
