Generic Dijkstra is a novel algorithm for finding the optimal shortest path in both wavelength-division multiplexed networks (WDM) and elastic optical networks (EON), claimed to outperform known algorithms considerably. Because of its novelty, it has not been independently implemented and verified. ...
The Dijkstra algorithm has the advantage of the capability of finding the shortest path between two locations, however, when performing a complete exploration of the environment presents problems of the computational cost, where the complexity of the problem increases. Thus, it is established that the...
英文回答：Dijkstra's Algorithm is a graph search algorithm that finds the shortest paths from a single source vertex to all other vertices in a weighted graph. It is a greedy algorithm that iteratively constructs a shortest path tree by selecting the vertex withthe smallest distance from the ...
