Which search strategy is also called as blind search? A. Uninformed search B. Informed search C. Simple reflex search D. All of the mentioned

The correct answer is A. Uninformed search.

Uninformed search is also called blind search because it does not use any knowledge of the problem domain to guide the search process. Instead, it explores all possible states of the search space, regardless of whether they are likely to lead to the goal state.

Informed search, on the other hand, uses knowledge of the problem domain to guide the search process. This knowledge can

be in the form of heuristics, which are rules of thumb that estimate the cost of reaching a goal state from a given state. Informed search can be much more efficient than uninformed search, as it can avoid exploring states that are unlikely to lead to the goal state.

Simple reflex search is a type of uninformed search that explores the search space in a depth-first manner. This means that it always expands the most recently explored node first. Simple reflex search is often used in simple problems where there is no need to use more sophisticated search techniques.

All of the mentioned are uninformed search strategies.
