Can A* search guarantee finding the optimal solution for all problem instances? Explain why or why not.
- A* search cannot guarantee optimality in all cases
- A* search is only applicable to specific problems
- No, it depends on the specific heuristic used
- Yes, A* search always finds the optimal solution
A* search does not guarantee finding the optimal solution for all problem instances. While it is complete and optimal in theory, the guarantee depends on the admissibility of the heuristic function. If the heuristic is admissible, A* is guaranteed to find the optimal solution; otherwise, optimality is not assured.
