Study Notes
Worst Case Analysis
- Worst-case scenario is evaluated to determine the upper limits of algorithm performance.
- Compare operations are essential for determining element order and conditions within algorithms.
Compare Operations
- The total number of compare operations executed in the worst case will depend on the specific algorithm analyzed.
- The calculation for compare operations typically involves understanding the input size and the algorithm's complexity.
Copy Operations
- Copy operations are necessary when elements need to be shifted, duplicated, or rearranged in memory.
- Similar to compare operations, the worst-case number of copy operations is algorithm-dependent.
Total Operations
- The total number of operations (compare + copy operations) provides a comprehensive view of algorithm efficiency.
- Analyzing total operations helps in assessing the scalability of algorithms, particularly in larger datasets.
