How can we improve Dijkstra's algorithm for better performance?

There are several ways to enhance Dijkstra's algorithm, such as using a priority queue or implementing bidirectional search.

What is a priority queue and how does it help?

A priority queue is a data structure that allows for efficient retrieval of the highest (or lowest) priority element, which speeds up the selection of the next node to process in Dijkstra's algorithm.

Can you explain bidirectional search?

Bidirectional search runs two simultaneous searches: one forward from the start node and one backward from the target node, meeting in the middle, which can significantly reduce the search space.

Are there any other algorithms that can be used instead of Dijkstra's?

Yes, algorithms like A* and Bellman-Ford can be used as alternatives, depending on the specific requirements and constraints of the problem.
