Particularly, you can find the shortest path from a node (called the "source node") … SpletThe start node has an initial lowest cost of 0. The algorithm concludes when the goal node G is removed from the open list and explored, indicating that a shortest path has been found. The shortest path is the path from the start node S to the goal node G in the tree.
