WebApr 27, 2024 · Breath First Search to solve Eight puzzle problem. Note: If we solve this problem with depth first search, then it will go to depth instead of exploring layer wise nodes. Time complexity: In worst case time complexity in BFS is O(b^d) know as order of b raise to power d. In this particular case it is (3^20). b-branch factor. d-depth factor. Let ... 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.’
