"WebOct 4, 2024 · Solution: As edge weights are unique, there will be only one edge emin and that will be added to MST, therefore option (A) is always true. As spanning tree has minimum number of edges, removal of any edge will disconnect the graph. Therefore, option (B) is also true. As all edge weights are distinct, G will have a unique minimum spanning … " - Dijkstra algorithm practice problems

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. Both methods search for the shortest route by moving around the network and investigating (or attaching) nodes. When the algorithms are begun from the same node s, the sequence in which the nodes are ...
