What are some optimizations for Dijkstra's algorithm?
Some common optimizations include using a priority queue, bidirectional search, and A* heuristics.
How does using a priority queue improve performance?
A priority queue allows for faster retrieval of the next node with the smallest tentative distance, reducing overall time complexity.
Can you explain bidirectional search?
Bidirectional search runs two simultaneous searches: one from the start and one from the goal, meeting in the middle, which can significantly reduce the search space.
What is the A* algorithm and how is it related?
A* is an extension of Dijkstra's algorithm that uses heuristics to guide the search, making it more efficient in many cases.
