WebFeb 8, 2024 · Depending on the f(n), we have two informed search algorithms as greedy search and A* search algorithms. 2.1 Greedy Search Algorithms. In greedy search, the heuristic values of child nodes are ... Webbreadth-first search is optimal if the path cost is a nondecreasing function of the depth of the node. The most common such scenario is that all actions have the same cost. From that I understand that if the path cost is non decreasing function of depth, the BFS algorithm returns an optimal solution, i.e., the only condition is the cost ...
