WebNov 8, 2024 · For example, we won’t get an optimal algorithm if we use only a heuristic to order the frontier. If we use the negative depth, we get DFS, which isn’t a complete algorithm. However, if we use the depth of a node as the evaluation function, we get Breadth-First Search, which is completely under certain conditions. 6. Discussion WebAug 9, 2024 · For Greedy BFS the evaluation function is f (n) = h (n) while for A* the evaluation function is f (n) = g (n) + h (n).

BFS … WebMay 18, 2024 · BFS v/s Greedy BFS. BFS expands the most promising node first(by looking at it's proximity to the source node).Hence, the solution is thorough. It might have to return back in path if a dead end is reached. Whereas, Greedy BFS uses heuristics to prioritize nodes closer to target. Hence, the solution is faster(but not necessarily optimal).
