Explanation

What does the iterative deepening part of IDDFS refer to?

a: The search depth limit is increased incrementally after each iteration. Explanation

Explanation

b: IDDFS re-starts the search from the root after each iteration. Explanation

Explanation

c: IDDFS uses a breadth-first approach in each iteration. Explanation

Explanation

d: IDDFS explores the entire search space before increasing the depth limit. Explanation

Explanation

What is the time complexity of IDDFS in terms of the branching factor (b) and the depth of the goal node (d)?

a: O(b^d) Explanation

Explanation

b: O(d^b) Explanation

Explanation

c: O(d * b^d) Explanation

Explanation

d: O(b^d * d) Explanation

Explanation

When is IDDFS not complete?

a: When the goal node is not reachable from the source vertex Explanation

Explanation

b: When the state space is infinite Explanation

Explanation

c: Either a) or b) Explanation

Explanation

d: It is always complete Explanation

Explanation

In which cases would IDDFS be preferred over DFS?

a: When memory usage needs to be controlled. Explanation

Explanation

b: When the goal node is at a shallow depth and the graph has a high depth. Explanation

Explanation

c: When the goal node is at a deep depth and the graph has a high branching factor. Explanation

Explanation
