Study Notes
Search Techniques
- Exhaustive search techniques systematically evaluate every path in the search space.
Heuristics in Search Algorithms
- The main purpose of using a heuristic is to guide the search towards more promising areas of the search space.
Hill-Climbing Algorithms
- Steepest-ascent hill-climbing selects the best possible move at each point and requires all child nodes to be generated first.
Beam Search
- Beam search involves selecting a fixed number of best nodes (beam width) to expand at each level, unlike other hill-climbing algorithms.
Search Strategies
- Optimal search strategies are used to find the best or shortest route.
