Advanced Topic 46 of 51 AI & Machine Learning

Search Algorithms in AI

Exploring state spaces for goal states.

How it works

State-space search uses uninformed (BFS, DFS, uniform-cost) and informed (greedy, A*) strategies; local search (hill climbing, genetic algorithms) handles huge spaces.

Where it is used

Planning and puzzles.

Common pitfall

Heuristics must be admissible for optimal A*.

Where it fits in the course

Search Algorithms in AI is topic 46 of 51 in AI & Machine Learning, rated Advanced. It follows Tokenization. The next topic is Minimax and Alpha-Beta.
