"WebDec 4, 2011 · Greedy BFS is greedy in expanding a potentially better successor of the current node. The difference between the two algorithms is in the loop that handles the evaluation of successors. Best-first search always exhausts the current node's successors by evaluating them and continues with the best one from them: 4. For each successor do: a. " - Greedy bfs in python
