The decremental single-source shortest paths (SSSP) problem concerns maintaining the distances between a given source node s to every node in an n-node m-edge graph G undergoing edge deletions. While its static counterpart can be easily solved in near-linear time, this decremental problem is mu...

This paper investigates two types of graph queries: single source distance (SSD) queries and single source shortest path (SSSP) queries. Given a node v in a graph G, an SSD query from v asks for the distance from $v$ to any other node in G, while an SSSP query retrieves the shortest...
摘要: Given an n-vertex directed network G with real costs on the edges and a designated source vertex s, we give a new algorithm to compute shortest paths from s. Our algorithm is a simple deterministic on关键词: Practical, Theoretical or Mathematical/ computational geometry directed graphs/ ...
Each cell is modeled as a node in a graph and edges are created only between selected pairs of cells. Problem specific priors can be introduced in the algorithm by choosing which edges to instantiate. The 2D embedding is then computed using a standard force directed graph layout technique. ...
