This article presents a Java … WebOct 8, 2012 · In shortest-path algorithms, a high cost tells the algorithm "do not go down that path". So by default, we only know that the starting node is apart of the shortest path, while all other nodes are still undetermined. Therefore, we assign a low cost of zero to the starting node (e.g. S), and a high cost of infinity to every other node (e.g. A, E).
