The single source shortest path algorithm (for arbitrary weight positive or negative) is also known Bellman-Ford algorithm is used to find minimum distance from source vertex to any other vertex. The main difference between this algorithm with Dijkstra’s algorithm is, in Dijkstra’s algorithm we ...
1) single source shortest path 单源最短路径1. For the first time, this paper proposes an efficient algorithm for single source shortest path in complex networks and graphs, by labeling the nodes with its current shortest distance from the source in depth first search. 提出在深度优先搜索过程...
All - pairs shortest - paths problem:Find the shortest path from u to v for every pair of vertices u and v. Running a single - source algorithm once from each vertex can clarify this problem; but it can generally be solved faster, and its structure is of interest in the own right. ...
In this project, you will parallelize single source shortest path (SSSP) algorithm on GPUs. A SSSP algorithm finds the shortest path between two vertices in a graph. It is an important and also an interesting problem that admit many potential algorithmic choices. SSSP can find its uses in man...
Must be one of: "inbound" or "oubound". concurrency (optional) –type: 0 or 1; default: 0. Controls the number of concurrent threads used to run the algorithm. If set to 0, uses all available threads to complete execution of the individual algorithm invocation. If set to 1, uses a...
While its static counterpart can be easily solved in near-linear time, this decremental problem is much more challenging even in the undirected unweighted case. In this case, the classic O(mn) total update time of Even and Shiloach (JACM 1981) has been the fastest known algorithm for three ...
