WebMay 20, 2012 · Djikstra's Algorithm uses the parent array to track the shortest path from start to end. You'd start at parent[end] and follow the entries of the array until you got back to start. Some pseudocode: WebDijkstra’s algorithm. Dijkstra’s shortest path algorithm is an algorithm which is used for finding the shortest paths between nodes in a graph, for example, road networks, etc. This algorithm is a generalization of the BFS algorithm. The algorithm works by keeping the shortest distance of vertex v from the source in the distance table.
