How does the choice of heuristic function impact the performance of the A* search algorithm?

  • A heuristic always degrades performance
  • A well-designed heuristic improves efficiency
  • Heuristics are only used in specific cases
  • The heuristic has no impact on performance
The choice of heuristic function significantly impacts the performance of the A* search algorithm. A well-designed heuristic can guide the algorithm efficiently towards the goal, reducing the search space. On the other hand, a poorly chosen heuristic may lead to suboptimal or inefficient paths, affecting the algorithm's overall performance.
