A class of general-purpose search algorithms which operates in brute force-way. Uninformed search algorithms do not have additional information about state or search space other than how to traverse the tree, so it is also called blind search. Following are the various types of uninformed search algorithms: Depth-first Search (DFS), Depth-limited Search (DLFS), Iterative deepening depth-first search (IDDFS), Breadth-first Search (BFS), Bidirectional Search (BS), Uniform cost search (UCS), Backtracking (BT), Forward checking (FC).
