Motion planning is a core problem in robotics concerned with finding feasible paths for a given robot. Motion planning algorithms perform a search in the high-dimensional continuous space of robot configurations and exemplify many of the core algorithmic concepts of search algorithms and associated data structures. Motion planning algorithms can…

Tying teachers' pay to their classroom performance should, says Victor Lavy, improve the current educational system both by clarifying teaching goals and by attracting and retaining the most productive teachers. But implementing pay for performance poses many practical challenges, because measuring individual teachers' performance is difficult.…
