What is a state space in AI search?

It's the universe of all possible configurations — positions, board setups, locations — your problem lives in. **How does the A* algorithm work?** Prioritizes nodes by past cost plus optimistic guess to goal; explores promising paths first, finds optimal if heuristic's admissible.

Why use search-based AI over deep learning?

Search guarantees solutions (if feasible), optimal ones often; DL approximates black-box style, shines pattern-matching not planning.
