Which search strategy is also called a blind search?
Correct Answer
A. Uninformed search
Explanation
The term "blind search" refers to a search strategy where the algorithm has no information about the problem or the state space being searched. Uninformed search is a type of search strategy where the algorithm has no knowledge or heuristic information about the problem domain, and it explores the search space without any guidance. Therefore, uninformed search is also known as a blind search.

How many successors are generated in backtracking search?
Correct Answer
A. 1
Explanation
Backtracking search generates only one successor at a time. It explores a path until it reaches a dead end or finds a solution. If it reaches a dead end, it backtracks to the previous decision point and explores another path. This process continues until a solution is found or all possible paths have been explored. Therefore, only one successor is generated in backtracking search.
