Approximate Range Searching in External Memory
In this paper, we present two linear-size external memory data structures for approximate range searching. Our first structure, the BAR-B-tree, stores a set of N points in Rd and ...

Approximate Distance Oracles for Graphs with Dense Clusters
Let G be a graph containing N disjoint t-spanners that are inter-connected with M edges. We present an algorithm that constructs a data structure of size O(M2 + n log n) that answ...

Levelwise Mesh Sparsification for Shortest Path Queries
Shortest path query is a problem to answer the shortest path from the origin to the destination in short time. The network is fixed, and the goal of the study is to develop efficie...

Dynamic Range Reporting in External Memory
In this paper we describe a dynamic external memory data structure that supports range reporting queries in three dimensions in O(log2 B N + k B ) I/O operations, where k is the nu...

Dynamic Multi-level Overlay Graphs for Shortest Paths
Multi-level overlay graphs represent a speed-up technique for shortest paths computation which is based on a hierarchical decomposition of a weighted directed graph G. They have b...
