Question: Accurate heuristics dont necessarily reduce search time in the worst case. Given any depth d, define a search problem with a goal node at depth

Accurate heuristics don’t necessarily reduce search time in the worst case. Given any depth d, define a search problem with a goal node at depth d, and write a heuristic function such that |h(n) − h^∗ (n)| ≤ O(log h^∗ (n)) but A^∗ expands all nodes of depth less than d.
