Question
The maximum number of times the decrease key operation performed in Dijkstra’s algorithm will be equal to ___________
Solution
The maximum number of times the decrease key operation is performed in Dijkstra’s algorithm is equal to the number of edges in the graph. This is because in the worst case, every edge will be relaxed once. Relaxing an edge involves decreasing the key of a vertex. Therefore, in the worst case, the decrease key operation can be performed as many times as there are edges in the graph.
