"WebDec 12, 2024 · 2 Answers. Sorted by: 4. The "non visited vertex with the smallest d [v]" is actually O (1) if you use a min heap and insertion in the min heap is O (log V). Therefore the complexity is as you correctly mentioned for the other loops: O ( (V logV) + (E logV)) = O (E logV) // Assuming E > V which is reasonable. Share. " - Explain the dijkstra's algorithm
