This can happen if the algorithm gets stuck in a cycle or if the search … WebFeb 20, 2024 · The heuristic can be used to control A*’s behavior. At one extreme, if h (n) is 0, then only g (n) plays a role, and A* turns into Dijkstra’s Algorithm, which is guaranteed to find a shortest path. If h (n) is always lower than (or equal to) the cost of moving from n to the goal, then A* is guaranteed to find a shortest path. dial a story library
