WebOct 8, 2012 · Relaxing an edge, (a concept you can find in other shortest-path algorithms as well) is trying to lower the cost of getting to a vertex by using another vertex. You are calculating the distances from a beginning vertex, say S, to all the other vertices. At some point, you have intermediate results -- current estimates. WebOne algorithm for finding the shortest path from a starting node to a target node in a weighted graph is Dijkstra’s algorithm. The algorithm creates a tree of shortest paths from the starting vertex, the source, to all other points in the graph. Dijkstra’s algorithm, …

"WebDijkstra’s algorithm. Dijkstra’s shortest path algorithm is an algorithm which is used for finding the shortest paths between nodes in a graph, for example, road networks, etc. This algorithm is a generalization of the BFS algorithm. The algorithm works by keeping the shortest distance of vertex v from the source in the distance table. " - Dijstela

Dijkstra's algorithm is an algorithm for finding the shortest paths between nodes in a weighted graph, which may represent, for example, road networks. It was conceived by computer scientist Edsger W. Dijkstra in 1956 and published three years later. The algorithm exists in many variants. Dijkstra's original algorithm found the shortest path between two given nodes, but a more common variant fixes a single node as the "source" node …

WebThe shortest route (in terms of cost) between any two nodes in a graph may be discovered using either the Dijkstra's method or the Prim algorithm.
