Witnesses for Boolean Matrix Multiplication and for Shortest Paths
Abstract Summary of results The subcubic (O(n ) for < 3) algorithms to multiply Boolean matrices do not provide the witnesses; namely, they compute C = AB but if Cij = 1 they d...

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...

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 ...

Fast Dichotomic Multiple Search Algorithm for Shortest Cirular Path
Circular shortest path algorithms for polar objects segmentation have been proposed in [1, 11, 10] to address discrete case and extended in [2] to the continuous domain for closed...
