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. …
