Convex Hulls and Triangulations of Planar Point Sets on the Congested Clique.
(2023) 35th Canadian Conference on ComputationalGeometry, CCCG 2023 p.183-189
- Abstract
- We consider geometric problems on planar n2-point sets in the congested clique model. Initially, each node in the n-clique network holds a batch of n distinct points in the Euclidean plane given by Ο(log n)-bit coordinates. Ineach round, each node can send a distinct Ο(log n)-bit message to each other node in the clique and perform unlimited local computations. We show that the convex hull of the input n2-point set can be constructed in Ο(min{h, log n}) rounds, where h is the size of the hull, on the congested clique. We also show that a triangulation of the input n2 -point set can be constructed in Ο(log2n) rounds on the... (More)
