The correct answer is: D. All of the mentioned
Informed search, best first search, and heuristic search are all search strategies that use problem-specific knowledge 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, or it can be in the form of a map of the search space.
Informed search is a general term for any search strategy that uses problem-specific knowledge. Best first search is a specific type of informed search that uses
a heuristic function to estimate the cost of reaching a goal state from a given state. Heuristic search is a general term for any search strategy that uses heuristics to guide the search process.Informed search is often more efficient than uninformed search, which does not use problem-specific knowledge. However, informed search can also be more complex to implement.
Here is a brief explanation of each option:
- Informed search is a search strategy that uses problem-specific knowledge 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, or it can be in the form of a map of the search space.
- Best first search is a specific type of informed search that uses a heuristic function to estimate the cost of reaching a goal state from a given state. The heuristic function is used to guide the search process by selecting the state with the lowest estimated cost to the goal state.
- Heuristic search is a general term for any search strategy that uses heuristics to guide the search process. Heuristics can be used to estimate the cost of reaching a goal state from a given state, or they can be used to rank states in order of their estimated cost to the goal state.
