WebFeb 12, 2024 · While I am reading, at some points, I found GBFS similar to DFS. It expands the whole branches and goes after one according to the heuristic function. It doesn't expand the rest like BFS. Perceiving this as similar to what depth-first search does, I understand that the worst time complexity is $\mathcal{O}(b^m)$. But I don't understand the ... WebAnswer (1 of 3): Greedy algorithms make the optimal choice at each step as it attempts to find the overall optimal way to solve the entire problem.

Breadth First Search vs Greedy Algorithm - Stack Overflow

Using a greedy algorithm, expand the first successor of the parent. After a successor is generated: 1. If the successor's heuristic is better than its parent, the successor is set at the front of the queue (with the parent reinserted directly behind it), and the loop restarts. 2. Else, the successor is inserted into the queue (in a location determined by its heuristic value). The procedure will evaluate the remaining successors (if any) of the parent. WebMay 22, 2024 · Display it. Insert it in a queue. Rule 2 − If no adjacent vertex is found, then remove the first vertex from the queue. Rule 3 − Repeat Rule 1 and Rule 2 until the queue is empty.
