How can I optimize the A* algorithm in C++?

How can I optimize the A* algorithm in C++?

To optimize the A* algorithm, consider using a more efficient data structure for the open set, like a priority queue.

What data structure do you recommend for the open set?

A binary heap or a Fibonacci heap can significantly improve the performance of the open set operations.

Are there any heuristics that work better than others?

Yes, using heuristics like Manhattan distance for grid-based maps or Euclidean distance for continuous spaces can enhance performance.

How do I implement a priority queue in C++?

You can use the STL's std::priority_queue or implement your own using a vector and heap functions.
