Web• 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 … Dijkstra's algorithm is an algorithm for finding the shortest paths between nodes in a weighted graph, which may represent, for example, road networks.
