- Abstract:
-
In this paper, research and analysis on the basis of the l)ijkstra algorithm, the Dijkstra algorithm byintroducing the vertex of cut sets and cut the vertex of idea to improve the Dijkstra algorithm, this method firsvertex eut-set or cut vertex to the original problem is decomposed into multiple sub-graph, then the shortes!path on each sub-graph parallel to the shortest path of the original problem , and finally obtained by the vertexcut-set or cut vertex, which reduces the time complexity of the algorithm and improves the efficieney of the al-gorithm.
