• Claim: At end of Dijkstra’s algorithm, d(s, v) = δ(s, v) for all v ∈ V • Proof: – If relaxation sets d(s, v) to δ(s, v), then d(s, v) = δ(s, v) at the end of the algorithm ∗ Relaxation can only decrease estimates d(s, v) ∗ Relaxation is safe, i.e., maintains that each d(s, v) is weight of a path to v (or ∞)

The main ...

The Dijkstra algorithm uses labels that are positive integers or real numbers, which are totally ordered. It can be generalized to use any labels that are partially ordered, provided the subsequent labels (a subsequent label is produced when traversing an edge) are monotonically non-decreasing.

Dijkstra's algorithm maintains a set S (Solved) of vertices whose final shortest path weights have been determined. Initially S = {s} , the source vertex s only. Then, it repeatedly selects vertex u in {V\S} with the minimum shortest path estimate, adds u to S , and relaxes all outgoing edges of u .
