Which one of the following is not an informed search technique?
Answer : DFS
Hill Climbing : It is an iterative algorithm that starts with an arbitrary solution to a problem, then attempts to find a better solution by incrementally changing a single element of the solution. If the change produces a better solution, an incremental change is made to the new solution, repeating until no further improvements can be found.

Uninformed search is an Exhaustive search using brute force methods: search all possible paths
Eg: depth-first, Breadth-first
Other options are informed search.
informed search used Heuristic approaches (choose path likely to give solution)
