    Study Notes

    • Algorithms are a set of rules for calculating inputs to produce outputs, defined by the mathematician Al-khowarizmi
    • Algorithms are designed with building blocks: sequencing, selection, and iteration
    • Time complexity is a concept used to evaluate algorithm efficiency
    • Analysis of algorithms compares their complexity to determine which is best
    • Computing problems are categorized based on their solving approach
    • Algorithms can be deterministic (predictable) or stochastic (random)
    • This unit covers the basics of algorithms and their properties
    • Objectives of the unit include defining algorithms and their properties, designing algorithms, and understanding time and space complexity and deterministic vs stochastic algorithms.
    • An algorithm is a collection of tasks written in common language, producing output within a time frame, and independent of programming language
    • Properties of a good algorithm include having a finite number of inputs, producing output, a definite sequence of operations, every step being basic and essential, and finishing in a finite number of steps.
