Improved distance queries in planar graphs

  title={Improved distance queries in planar graphs},
  author={Yahav Nussbaum},
There are several known data structures that answer distance queries between two arbitrary vertices in a planar graph. The tradeoff is among preprocessing time, storage space and query time. In this paper we present three data structures that answer such queries, each with its own advantage over previous data structures. The first one improves the query time of data structures of linear space. The second improves the preprocessing time of data structures with a space bound of O(n) or higher… CONTINUE READING
