A* search is complete. 4. Optimal. Best-first search is not optimal as the path found may not be optimal. A* search is optimal as the path found is always optimal. 5. Time and Space Complexity. Its time complexity is O (b m) and space complexity can be polynomial.

WebAs what we said earlier, the greedy best-first search algorithm tries to explore the node that is closest to the goal. This algorithm evaluates nodes by using the heuristic function h(n), that is, the evaluation function is equal to the heuristic function, f(n) = h(n). This equivalency is what makes the search algorithm ‘greedy.’
