Study Notes
Search Algorithms in AI
- Search algorithms are used by AI agents to find solutions to problems by exploring the problem space.
- Both uninformed and informed search strategies are essential for effective problem-solving in AI contexts.
Uninformed Search Algorithms
- Also known as blind search algorithms, these do not utilize any domain knowledge.
- They systematically explore all possible solutions until a valid solution is found or all possibilities are exhausted.
- Implementation is straightforward as they depend on defined problem parameters and basic rules.
- These algorithms guarantee a solution if one exists within the problem space.
Features of Uninformed Search Algorithms
- Lack of prior knowledge about states or actions associated with the problem.
- Explore the problem space without any heuristic guidance.
- Easy to implement and understand, offering a basic approach to finding solutions.
Breadth First Search (BFS)
- BFS explores neighboring nodes of the initial node in a level-by-level manner.
- Traversal spreads out wide, ensuring that all nodes at the current level are visited before moving deeper into the graph.
- Effective for finding the shortest path in unweighted graphs, as it visits all reachable nodes systematically.
Queue for Level-Wise Search
- A queue follows the First-In-First-Out (FIFO) structure, where the first element added is the first one to be removed.
- In BFS, begin with the root node, push it to the queue, mark it as visited, and print it.
- Continue processing until the queue is empty, removing the front node and adding its neighboring nodes to the queue for further exploration.
