Solution
The search that is complete and optimal when h(n) is consistent is A* search.
Here's why:
-
A* search is a complete search algorithm, meaning it is guaranteed to find a solution if one exists.
-
It is also optimal, meaning it is guaranteed to find the least-cost solution. This is because it uses a heuristic function h(n) to estimate the cost to reach the goal from node n.
-
When h(n) is consistent (or "admissible"), it never overestimates the cost to reach the goal. This means A* search will always find the shortest (least-cost) path to the goal.
So, the answer is A* search.
