Optimization and Application of Dijkstra Algorithm for
the Shortest Path
Abstract:Dijkstra algorithm is a classic arithmetic for the shortest path.It is the academic foundation that many engineerings were solved in the shortest path is use.When a shortest path between nodes is searched with Dijkstra algorithm,a lot of nodes away from lagged nodes are involved,so that the efficiency of Dijkstra algorithm is low.An optimization algorithm is presented in this paper based on analysis of Dijkstra algorithm.Only these nodes that the neighbor of nodes in the shortest path are processed, Therefore,the number of processed nodes is largely reduced in the optimization algorithm,and efficiency of the optimization algorithm is improved.
Key Words:the shortest path; Dijkstra algorithm; optimization algorithm
