WebNov 25, 2024 · The shortest path between node 0 and node 3 is along the path 0->1->3. However, the edge between node 1 and node 3 is not in the minimum spanning tree. Therefore, the generated shortest-path tree is different from the minimum spanning tree. Similar to Prim’s algorithm, the time complexity also depends on the data structures used … 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.
