Question

G = (V, E). 

State the order of vertices by when the verties are deleted from the min heap (Dijkstra’s Algorithm is applied on G with s as the starting vertex).Then you can edit the length of edge (a, d) but when Dijkstra’s Algorithm is applied on the new graph (s is the starting vertex), the order of vertices being removed from the heap needs to be the same as before. Give the range in an interval form for a possible new length of edge (a, d).

Expert Solution
Step 1: Some Overviews
1. Order of Vertex Removal (starting from 's'):
  • The priority queue will dequeue the vertex with the shortest distance. Vertex
  • a
  • with distance 1 is dequeued first.
  • Now, for each of
  • a
  • 's neighbors (excluding
  • s
  • since we don't traverse backwards in Dijkstra), we check if the path through
  • a
  • offers a shorter path than what's already recorded. For vertex
  • c
  • , the path through
  • a

  • is shorter than the direct path from
  • s
  • to
  • c
  • which is 7. So, dist(
  • c
  • ) is updated to 3. dist(
  • d
  • ) is set to 5 as there's no previous value other than ∞.
  • Next,
  • c
  • with the updated distance 3 is dequeued, followed by
  • d
  • with distance 5, and finally
  • b
  • with distance 7.
