WebProof of Correctness Dijkstra’s algorithm is greedy: it makes a sequence of locally optimal moves, which results in the globally optimal solution. Specifically: It is not obvious that there cannot still be a shorter path to the Frontier node with smallest d-value. WebNov 30, 2024 · Both the algorithm and the proof of correctness where established by Esther Dijkstra this was back in the late 1950s.

It’s a great exercise to prove that this indeed is the case; it’s basically a generalization of the regular proof of correctness for Dijkstra’s algorithm. (This generalizes the excellent answer by @nir shahar.) WebProof by induction is a technique that works well for algorithms that loop over integers, and can prove that an algorithm always produces correct output. Other styles of proofs can verify correctness for other types of algorithms, like proof by contradiction or … fishermen\u0027s source
