The simulation results show that the proposed method is better than Dijkstra algorithm when the network routing graph holds many nodes. With the nodes number of the network increasing, the number of iterations of our algorithm will basically hold the line. The method shows better computational ...

Moreover, we analyze the maximum length of the disjoint paths. Experimental results show that our proposed algorithm performs better than the classical algorithm Dijkstra in the Average Running Time (ART) and is very close to that in the Average Path Length (APL). 展开 ...
Prim algorithm is a greedy approach, it is quite similar to Dijkstra algorithm) The algorithm goes as follows: 1.Mark all nodes with a cost and a parent (i.e. in an array). 2.The source node has a cost of 0 and all other node has cost of infinity. 3.While there is an unvisite...
Experimental results indicate that the proposed algorithm has better performance than Dijkstra algorithm in term of both solution quality and computational time, and thus it is a viable approach to mobile robot global path planning./span/span/span/p...
The implementation of Dijkstra's algorithm with the Fibonacci-heap data structure is better for dense graphs, where each vertex has an edge to almost every other vertex.DSA Exercises Test Yourself With Exercises Exercise: Using Dijkstra's algorithm to find the shortest paths from vertex C in ...
We cannot use Dijkstra's algorithm, which cannot handle graphs with negative-weight edges. Rather than finding the shortest path, these algorithms discover the longest path. If we do not want to alter any attributes in the graph, we can alter the algorithm by initializing the value of est(v...
When h(n) = 0, the A-star algorithm degenerates to the Dijkstra algorithm. While h(n) is much larger than g(n), the A-star algorithm is transformed into the DFS algorithm. If the actual h(n) differs from the ideal h(n), the operating efficiency of the A-star algorithm is ...
Dijkstra’s Minimal Spanning Tree AlgorithmGiven a connected, undirected graph with weighted edges, the objective is to find a tree, known as the minimal spanning tree (MST), that connects all vertices such that the sum of its edge weights is minimized....
At the same time, if we use algorithms for general graphs, then we do not get better results. The time complexity of best implementations of Dijkstra's algorithm with Fibonacci heap is O ( m + n log n ). 展开 关键词: quantum algorithms graph theory shortest path search query model ...
