(part 3)All these search algorithms are the same except for fringe strategiesConceptually, all fringes are priority queues (i.e. collections of nodes with attached priorities)Practically, for DFS and BFS, you can avoid the log(n) overhead from an actual priority queue, by using stacks and ...
As the name ‘Uninformed Search’ means the machine blindly follows the algorithm regardless of whether right or wrong, efficient or in-efficient.These algorithms are brute force operations, and the…

Uninformed Search methods, on the other hand, systematically explore the search space and are typically slower due to lack of guidance. 6 Examples of Informed Search algorithms include A* and Greedy Best-First Search, which use heuristics to estimate the best path to a goal. Uninformed Search...
