WebBest-first search algorithm visits next state based on heuristics function f(n) = h with lowest heuristic value (often called greedy). It doesn't consider cost of the path to that particular state. All it cares about is that which next state from the current state has lowest heuristics. WebJul 22, 2024 · And recall that a best-first search algorithm will pick the node with the lowest evaluation function. So a greedy best-first search is a best-first search where f (n) = h (n). As an example, we will look for a path from A to Z using the greedy approach. Our heuristic values: h (A) = 366. h (E) = 380. h (J) = 100. h (N) = 80.
