Shortest Path Problem -- from Wolfram MathWorld

WebDec 4, 2024 · It is easy to prove that the shortest path between (s_in, t_out) in H is the same as the shortest path between (s,t) in the original graph G. The proof is based on the fact that any such path goes through the edge (v_in, v_out) in H if and only if the corresponding path in G goes through node v. WebLet's calculate the shortest path between node C and the other nodes in our graph: During the algorithm execution, we'll mark every node with its minimum distance to node C (our selected node). For node C, this distance is 0. For the rest of nodes, as we still don't know that minimum distance, it starts being infinity (∞): ...
