"WebMay 24, 2024 · @boylec1986 you provided the link to wikipedia. Did you even yourself read it? Of course a star is a special case of best first search. But bfs and a* are different. Criteria for bfs is to use f(n) and expand the node with lowest f(n). In simple bfs it is simply f(n) = h(n). A* also uses f(n) thats why it is a specisl case of bfs. " - Greedy bfs example

WebMay 11, 2024 · In the case of the greedy BFS algorithm, the evaluation function is f(n)=h(n), that is, the greedy BFS algorithm first expands the node whose estimated distance to the goal is the smallest. So, greedy BFS does not use the "past knowledge", i.e. g(n). Hence its connotation "greedy". In general, the greedy BST algorithm is not complete, that is ... WebMay 18, 2024 · BFS v/s Greedy BFS. BFS expands the most promising node first(by looking at it's proximity to the source node).Hence, the solution is thorough. It might have to return back in path if a dead end is reached. Whereas, Greedy BFS uses heuristics to prioritize nodes closer to target. Hence, the solution is faster(but not necessarily optimal).
