An Efficient Algorithm for 2D Euclidean 2-Center with Outliers
For a set P of n points in R2 , the Euclidean 2-center problem computes a pair of congruent disks of the minimal radius that cover P. We extend this to the (2, k)-center problem wh...

Succinct Representations of Arbitrary Graphs
Abstract. We consider the problem of encoding a graph with n vertices and m edges compactly supporting adjacency, neighborhood and degree queries in constant time in the log n-bit ...

Relative Convex Hulls in Semi-dynamic Subdivisions
Abstract. We present data structures for maintaining the relative convex hull of a set of points (sites) in the presence of pairwise non-crossing line segments (barriers) that subd...

Faster Steiner Tree Computation in Polynomial-Space
Given an n-node graph and a subset of k terminal nodes, the NP-hard Steiner tree problem is to compute a minimum-size tree which spans the terminals. All the known algorithms for t...

On the Size of the 3D Visibility Skeleton: Experimental Results
Abstract. The 3D visibility skeleton is a data structure used to encode global visibility information about a set of objects. Previous theoretical results have shown that for k con...

Improved Approximation Algorithms for Relay Placement
In the relay placement problem the input is a set of sensors and a number r 1, the communication range of a relay. In the one-tier version of the problem the objective is to place...

How Reliable Are Practical Point-in-Polygon Strategies?
We experimentally study the reliability of geometric software for point location in simple polygons. As expected, the code we tested works very well for random query points. Howeve...
