An Approximation Algorithm for Shortest Descending Paths
A path from s to t on a polyhedral terrain is descending if the height of a point p never increases while we move p along the path from s to t. No efficient algorithm is known to ...

Removing Local Extrema from Imprecise Terrains
In this paper, we study imprecise terrains, that is, triangulated terrains with a vertical error interval in the vertices. We study the problem of removing as many local extrema (...
