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. WebDec 4, 2011 · BFS is an instance of tree search and graph search algorithms in which a node is selected for expansion based on the evaluation function f(n) = g(n) + h(n), where g(n) is length of the path from the root to n and h(n) is an estimate of the length of the path from n to the goal node. In a BFS algorithm, the node with the lowest evaluation (i.e. …
