Greedy best-first search
Did you know?
WebBest first search is informed search and DFS and BFS are uninformed searches. In order to use informed search algorithm you need to represent the knowledge of the problem as heuristic function. Best first search is sometimes another name for Greedy Best First Search, but it may also mean class of search algorithms, that chose to expand the most ... WebFeb 20, 2024 · At the other extreme, if h(n) is very high relative to g(n), then only h(n) plays a role, and A* turns into Greedy Best-First-Search. Note: Technically, the A* algorithm should be called simply A if the heuristic is an underestimate of the actual cost.
