Shortest path computation and reachability computation are two of the most fundamental operations for managing and analyzing large graphs.Firstly, we focus on the problem of computing the shortest path distance in dynamic graphs, particularly on decremental updates (i.e., edge deletions), with the use of distance labeling techniques.We experimentally evaluate our algorithms using eleven real-world large graphs and confirm the effectiveness and efficiency of our approach.
To address this problem, dynamic algorithm that computes the shortest-path in response to updates is in demand.
In this paper, we focus on dynamic algorithms for shortest point-to-point paths computation in directed graphs with positive edge weights.
We experimentally verify that these dynamic algorithms significantly outperform their batch counterparts in response to small changes, using real-life data and synthetic data.
I have a graph on which I frequently need to know all shortest paths (or rather their lengths).
Unfortunately, there is little work on answering such queries for dynamic graphs.
