How does bidirectional A search algorithm improve efficiency by simultaneously exploring the search space from both the start and goal nodes?

The bidirectional A search algorithm improves efficiency by exploring the search space from both the start and goal nodes at the same time. This allows the algorithm to converge faster towards a solution by meeting in the middle, reducing the overall search space that needs to be explored.


How does the bidirectional A algorithm work to efficiently find the shortest path between two points in a graph by simultaneously exploring from both the start and goal nodes?

The bidirectional A algorithm efficiently finds the shortest path between two points in a graph by exploring from both the start and goal nodes simultaneously. It uses two separate searches that meet in the middle, reducing the overall search space and improving efficiency compared to traditional A algorithm.


Is Dijkstra's algorithm a greedy algorithm?

Yes, Dijkstra's algorithm is a greedy algorithm because it makes decisions based on the current best option without considering future consequences.


What is the fastest algorithm for finding the shortest path in a graph?
