What is iterative deepening DFS and can you give me some examples?

Iterative Deepening Depth-First Search (IDDFS) is a search algorithm that combines the depth-first search's space efficiency and breadth-first search's completeness. It repeatedly applies depth-limited search with increasing depth limits until it finds the goal.

Can you provide a simple example of how IDDFS works?

Sure! Imagine a tree where each node has two children. IDDFS starts at depth 0, exploring the root, then goes to depth 1, exploring the root's children, and continues this way until it finds the target node.

What are the advantages of using IDDFS over other search algorithms?

IDDFS uses less memory than breadth-first search and guarantees finding the shortest path in an unweighted graph, making it efficient for large search spaces.

Are there any scenarios where IDDFS is not the best choice?

Yes, IDDFS can be inefficient for very deep trees or when the solution is near the bottom, as it may take longer to reach deeper levels compared to other algorithms.
