Optimal Data Structures for Farthest-Point Queries in Cactus Networks

Consider the continuum of points on the edges of a network, i.e., a connected, undirected graph with positive edge weights. We measure the distance between these points in terms of the weighted shortest path distance, called the network distance. Within this metric space, we study farthest points and farthest distances. We introduce optimal data structures supporting queries for the farthest di...

Optimal Data Structures for Farthest-Point

6 Consider the continuum of points on the edges of a network, i.e., a connected, undirected graph 7 with positive edge weights. We measure the distance between these points in terms of the weighted 8 shortest path distance, called the network distance. Within this metric space, we study farthest points 9 and farthest distances. We introduce optimal data structures supporting queries for the far...

Efficient Farthest-Point Queries in Two-terminal Series-parallel Networks

Consider the continuum of points along the edges of a network, i.e., a connected, undirected graph with positive edge weights. We measure the distance between these points in terms of the weighted shortest path distance, called the network distance. Within this metric space, we study farthest points and farthest distances. We introduce a data structure supporting queries for the farthest distan...

On Farthest-Point Information in Networks

Consider the continuum of points along the edges of a network, an embedded undirected graph with positive edge weights. Distance between these points can be measured as shortest path distance along the edges of the network. We introduce two new concepts to capture farthest-point information in this metric space. The first, eccentricity diagrams, are used to encode the distance towards farthest ...

Farthest-Point Queries with Geometric and Combinatorial Constraints

In this paper we discuss farthest-point problems in which a set or sequence S of n points in the plane is given in advance and can be preprocessed to answer various queries efficiently. First, we give a data structure that can be used to compute the point farthest from a query line segment in O(log2 n) time. Our data structure needs O(n logn) space and preprocessing time. To the best of our kno...
