AI in Robotics

AI plays a significant role in robotics.
Time Complexity: A measure of the time required for an algorithm to complete its task.
Space Complexity: The maximum storage space needed during a search.

Search Algorithms

Search algorithms are classified as uninformed (blind search) or informed (heuristic search).
Uninformed search does not use domain knowledge, like the closeness of a goal, and operates in a brute-force manner.
Informed search uses domain knowledge and is more efficient than uninformed search.
Uninformed/Blind Search algorithms include:
- Breadth-first search
- Uniform cost search
- Depth-first search
- Iterative deepening depth-first search
- Bidirectional Search
Informed Search algorithms include:
- Greedy Search
- A* Search

Uninformed Search Algorithms

Breadth-first Search: Traverses a tree or graph by exploring nodes level by level.
Depth-first Search: Traverses a tree or graph by exploring as deep as possible before backtracking.
Depth-limited Search: Similar to depth-first but limits the depth of the search.
Iterative deepening depth-first search: Combines breadth-first and depth-first search by iteratively increasing the depth limit.
Uniform cost search: Searches for the lowest-cost path to a goal node.
Bidirectional Search: Searches forward from the start node and backward from the goal node simultaneously.

Informed Search Algorithms

Greedy Search: Uses a heuristic function to estimate the distance to the goal node.
A Search:* Combines the costs of reaching a node with the heuristic function.
- Advantages:
  - Best algorithm for finding solutions
  - Optimal and complete
  - Solves complex problems
- Disadvantages:
  - Doesn't always produce the shortest path.
  - Complexity issues.
  - High memory requirement.

Hill Climbing Algorithm

A local search algorithm used to find the peak of a mountain or the best solution to a problem.
Simple Hill Climbing: Evaluates neighboring nodes and selects the first one that improves the current state.
Steepest-Ascent Hill Climbing: Examines all neighboring nodes and selects the one closest to the goal state.

Means-Ends Analysis

A problem-solving technique used to limit the search in AI programs. - Combines backward and forward search techniques. - First introduced in 1961 in the General Problem Solver (GPS) program.
