"WebAug 9, 2024 · The only difference between Greedy BFS and A* BFS is in the evaluation function. For Greedy BFS the evaluation function is f(n) = h(n) while for A* the evaluation function is f(n) = g(n) + h(n). Essentially, since A* is more optimal of the two approaches as it also takes into consideration the total distance travelled so far i.e. g(n). " - Greedy function
