Greedy best-first
WebJan 19, 2024 · Greedy best-first search. Main idea: select the path whose end is closest to a goal according to the heuristic function. Best-first search selects a path on the frontier with minimal \(h\)-value. It treats the frontier as a priority queue ordered by \(h\). Greedy search example: Romania. This is not the shortest path! Greedy search is not optimal WebMay 26, 2014 · When Greedy Best-First Search finds the wrong answer (longer path), A* finds the right answer, like Dijkstra’s Algorithm does, but still explores less than Dijkstra’s Algorithm does. A* is the best of both worlds. As long as the heuristic does not overestimate distances, A* finds an optimal path, like Dijkstra’s Algorithm does.

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.
