πŸ“š Quick Study Guide

    πŸ” Algorithm robustness refers to the ability of an algorithm to handle errors, unexpected inputs, and stressful conditions during execution. πŸ›‘οΈ Robust algorithms should maintain functionality even when faced with noisy or incomplete data. 🌑️ Key types include: Input validation, exception handling, and fault tolerance. πŸ“ Input validation involves checking data before processing to ensure it meets expected criteria. 🐞 Exception handling involves identifying and dealing with errors that occur during program execution. βš™οΈ Fault tolerance involves building systems that can continue operating even if some components fail. πŸ’‘ Common techniques include redundancy, checkpointing, and error correction.

Practice Quiz

  1. Which of the following best describes algorithm robustness?

    3. C) The complexity of an algorithm's code.
    4. D) The amount of memory an algorithm requires.

  2. What is the purpose of input validation in algorithm robustness?
    1. A) To speed up the execution of the algorithm.
    2. B) To check if input data meets expected criteria.
    3. C) To reduce the memory usage of the algorithm.
