Webiii. Breadth-first search is always a complete search method, even if all of the actions have different costs. True - completeness refers to finding “a” solution, not the “best” iv. When hill-climbing and greedy best first search use the exact same admissible heuristic function, they will expand the same set of search nodes. Web• The choice of f determines the search strategy (one can show that best-first tree search includes DFS as a special case). • Often, for best-first algorithms, f is defined in terms of a heuristic function, h(n). h(n) = estimated cost of the cheapest path from the state at node n to a goal state. (for goal state: h(n)=0)

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.
