[PDF] dijkstra algorithm time and space complexity

The time complexity of Dijkstra's algorithm using a min heap as a min-priority queue is O((V + E) log V), where V is the number of vertices and E is the number of edges in the graph. This complexity arises from the repeated extraction of the minimum element from the min heap and the relaxation of outgoing edges.
