What is the best heuristic for A*?

What is the best heuristic for the A* search algorithm?

The best heuristic for A* depends on the problem. For example, in a grid, the Manhattan distance is often effective.

Can you explain why Manhattan distance works well?

Manhattan distance works well because it accurately reflects the cost of moving in a grid-based environment, where diagonal moves aren't allowed.

Are there other heuristics I should consider?

Yes, other heuristics include Euclidean distance and Chebyshev distance, depending on the movement allowed in your environment.

How do I choose the right heuristic for my specific problem?

Consider the nature of your problem, the movement costs, and whether you need an admissible heuristic to ensure optimality.
