Approximation Algorithms for Shortest Descending Paths in Terrains
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 ...

Partially Dynamic Concurrent Update of Distributed Shortest Paths
We study the dynamic version of the distributed all-pairs shortest paths problem. Most of the solutions given in the literature for this problem work under the assumption that bef...
