Dynamic shortest paths and transitive closure: Algorithmic techniques and data structures
In this paper, we survey fully dynamic algorithms for path problems on general directed graphs. In particular, we consider two fundamental problems: dynamic transitive closure and...

Heuristic Search for Generalized Stochastic Shortest Path MDPs
Research in efficient methods for solving infinite-horizon MDPs has so far concentrated primarily on discounted MDPs and the more general stochastic shortest path problems (SSPs...

A hybrid control approach to multi-robot coordinated path following
— The paper studies the coordinated path following problem, namely, steering a group of unicycles to a given path while achieving an inter-vehicle formation pattern. A novel hybr...

Timing Analysis with Implicitly Specified False Paths
We consider the problem of timing analysis in the presence of known false paths. The main difficulty in adaptation of classical breadth-first search to the problem is that at each...

Exploiting Graph Structure for Accelerating the Calculation of Shortest Paths in Wordnets
This paper presents an approach for substantially reducing the time needed to calculate the shortest paths between all concepts in a wordnet. The algorithm exploits the unique &qu...
