WebI understand that the dijkstra_path(G, source, target[, weight]) function is based on the dijkstra's shortest path algorithm. I would like to know the source algorithm upon which the shortest_path(G[, source, target, weight]) function is based. I need it because I have to report about the algorithms I have used.

WebDijkstra algorithm was conceived by computer scientist Edsger Dijkstra in 1956 is an algorithm to find the shortest paths between nodes in graph [3]. Dijkstra algorithm is an iterative algorithm that find the shortest path from source vertex to all other vertices in graph and it is greedy algorithm that rely on WebUnlike Dijkstra’s shortest path algorithm, the next node to search from is not solely picked on the already computed distance.Instead, the algorithm combines the already computed distance with the result of a heuristic function. That function takes a node as input and returns a value that corresponds to the cost to reach the target node from that node.
