Characterization of Polygons Searchable by a Boundary 1-Searcher
Suppose intruders are in a dark polygonal room and they can move at a finite but unbounded speed, trying to avoid detection. A boundary 1-searcher can move along the polygon bounda...

On Bipartite Matching under the RMS Distance
Given two sets A and B of n points each in R2 , we study the problem of computing a matching between A and B that minimizes the root mean square (rms) distance of matched pairs. W...

Polygons Flip Finitely: Flaws and a Fix
Every simple planar polygon can undergo only a finite number of pocket flips before becoming convex. Since Erdos posed this as an open problem in 1935, several independent purport...

Polygon Reconstruction from Line Cross-Sections
We study the following geometric probing problem: Reconstruct a planar polygon from its intersections with a collection of arbitrarily-oriented "cutting" lines. We propo...

Routing with Guaranteed Delivery on Virtual Coordinates
We propose four simple algorithms for routing on planar graphs using virtual coordinates. These algorithms are superior to existing algorithms in that they are oblivious, work als...

Bounded-Curvature Path Normalization
We present a new normal form for bounded-curvature paths that admits a combinatorial discription of such paths and a bound on the algebraic complexity of the underlying geometry.
