Depth Limited Search

Depth Limited Search is a search strategy. Say the data structure, whether it uses a heuristic, and if it guarantees a shortest path. Draw a tiny 6-node graph. That is the exam, not a textbook proof.

Depth Limited Search — output — three exam lines. Graph on paper first.

For Depth Limited Search: always mark visited nodes or you loop. Say complexity in plain words: time vs memory trade-off.

Exam tip

DS + heuristic yes/no + optimality.

Example

# Depth Limited Search
print("draw 6 nodes")
print("name the DS: queue / stack / priority")
print("say if the path is optimal")

Depth Limited Search — output: three exam lines. Graph on paper first.

RuleDepth Limited Search — visited set.
