WebMay 24, 2024 · Uniform cost is an uninformed search algorithm when Best First and A* search algorithms are informed search algorithms. Informed means that it uses a heuristic function for deciding the expanding node. Difference between best first search and A* is that best first uses f(n) = h(n) for expanding and A* uses f(n) = g(n)+h(n) for choosing the ... WebGreedy search (for most of this answer, think of greedy best-first search when I say greedy search) is an informed search algorithm, which means the function that is evaluated to choose which node to expand has the form of f(n) = h(n), where h is the heuristic function for a given node n that returns the estimated value from this node n to a ...
