Dijkstra's shortest-path algorithm

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 only decrease estimates d(s, v) ∗ Relaxation is safe, i.e., … WebMar 19, 2024 · A real-life example is presented with a given web map and distances from each connected node.
