The shortest path problem is a fundamental problem with numerous applications. In this paper we study one of the most common variants of the problem, where the goal is to find a …
Algorithms for route planning in transportation networks have recently undergone a rapid development, leading to methods that are up to three million times faster than Dijkstra's …
The single source shortest path problem for arbitrary directed graphs with n nodes, m edges and nonnegative edge weights can sequentially be solved using O (n· log n+ m) operations …
The design of approximation algorithms for spanning tree problems has become an exciting and important area of theoretical computer science and also plays a significant role in …
We study the point-to-point shortest path problem in a setting where preprocessing is allowed. We improve the reach-based approach of Gutman [17] in several ways. In …
We study the ALT algorithm [19] for the point-to-point shortest path problem in the context of road networks. We suggest improvements to the algorithm itself and to its preprocessing …
