    Study Notes

    AI Applications

    • AI has become increasingly advantageous in the healthcare industry within the last five to ten years.
    • AI can help doctors with diagnoses and inform patients when they are worsening.
    • AI can be used in gaming for strategic games like chess.
    • AI and finance industries are a good match; AI is implemented into financial processes for automation, chatbots, adaptive intelligence, algorithmic trading, and machine learning.
    • AI can be used in data security to determine software bugs and cyber-attacks.
    • AI can be used to manage and organize massive amounts of user profiles on social media platforms.
    • AI is used in travel and transport for tasks like making arrangements, finding hotels, flights, and the best routes.
    • AI is used in the automotive industry to provide virtual assistants and develop self-driving cars.

    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.
