WebApr 24, 2024 · The aim of BFS is reaching to a specified goal by using a heuristic function (it might be greedy) vs. HC is a local search algorithm ; BFS is mostly used in the graph search (in a wide state space) to find a path. vs. HC is using for the optimization task. WebA greedy algorithm is any algorithm that follows the problem-solving heuristic of making the locally optimal choice at each stage. [1] In many problems, a greedy strategy does not produce an optimal solution, but a greedy heuristic can yield locally optimal solutions that approximate a globally optimal solution in a reasonable amount of time.
