Question: for each ve V-(s) Q ? V while Q Q is a priority queue maintaining V-S do u ? EXTRACT-MIN(0) for each y e Adiu

for each ve V-(s) Q ? V while Q Q is a priority queue maintaining V-S do u ? EXTRACT-MIN(0) for each y e Adiu relaxation step then dv] From above Dijkstra's algorithm, what is the best order in which to process vertices, so that the estimates are guaranteed to converge to the true distances? That is, how does the algorithm select which vertex among the vertices of V-S to process next? (10 points) 6. How do we implement this selection of vertices efficiently? And what's the time complexity of InsertO, Extract-Min0 and Decrease-key0 operations from this? (10 points) 7
