A Single-Exponential Upper Bound for Finding Shortest Paths in Three Dimensions

Published

Journal Article

We derive a single-exponential time upper bound for finding the shortest path between two points in 3-dimensional Euclidean space with 1994 polyhedral obstacles. Prior to this work, the best known algorithm required double-exponential time. Given that the problem is known to be PSPACE-hard, the bound we present is essentially the best (in the worst-case sense) that can reasonably be expected. © 1994, ACM. All rights reserved.
