Best-first search is not optimal as the path found may not be optimal. A* search is optimal as the path found is always optimal. 5. Time and Space Complexity. Its time complexity is O (b m) and space complexity can be polynomial. WebNov 25, 2024 · Dijkstra’s algorithm uses this idea to come up with a greedy approach. In each step, we choose the node with the shortest path. We fix this cost and add this node’s neighbors to the queue. Therefore, the queue must be able to order the nodes inside it based on the smallest cost. We can consider using a priority queue to achieve this. grange hall baptist church marion il
