Title: Polygon reconstruction from local observations Speaker: Peter Widmayer Abstract: We study the problem of reconstructing an unknown simple polygon from a series of certain local observations, similar in spirit to the reconstruction of an unknown network by exploring it. For mobile agents that move in simple ways inside a polygon, we are interested in understanding what types of local observations carry enough information to allow polygon reconstruction. This is part of a more general effort to understand when and how simple primitives allow mobile agents to draw global conclusions about the environment from local observations.
