Study Notes
Algorithm Analysis in Computer Science
- Primarily concerned with the study of the performance of algorithms, focusing on their efficiency, scalability, and accuracy.
Efficiency of Algorithms
- An algorithm is considered efficient if its execution time and memory usage grow slowly as the input size increases.
Theoretical Analysis of Algorithms
- Commonly estimates the performance of an algorithm in terms of its computational complexity, which is the amount of time or space it requires as a function of the size of the input.
Best, Worst, and Average Case Descriptions
- Refers to the analysis of an algorithm's performance in different scenarios, including:
- Best case: the minimum time or space required by the algorithm to complete.
- Worst case: the maximum time or space required by the algorithm to complete.
- Average case: the typical or expected time or space required by the algorithm to complete.
Performance of Algorithms
- Usually described using the Big O notation, which provides an upper bound on the complexity of an algorithm, allowing for the comparison of different algorithms.
