Greedy algorithm - Wikipedia

A greedy algorithm is any algorithm that follows the problem-solving heuristic of making the locally optimal choice at each stage. 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. WebApr 4, 2024 · Heuristic Function: Greedy Best-First Search requires a heuristic function in order to work, which adds complexity to the algorithm. Lack of Completeness: Greedy Best-First Search is not a complete algorithm, meaning it may not always find a solution if one is exists.
