How is greedy best first search different from A*?

WebA greedy algorithm is an approach for solving a problem by selecting the best option available at the moment. It doesn't worry whether the current best result will bring the overall optimal result. The algorithm never reverses the earlier decision even if the choice is wrong. It works in a top-down approach. This algorithm may not produce the ... WebMay 11, 2024 · A* becomes impractical when the search space is huge.
