Greedy best first search vs hill climbing
WebAnswer (1 of 2): A greedy algorithm is called greedy because it takes the greediest bite at every step. An assumption is that the optimized solution for the first n steps fits cleanly … 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.
