Sorting Algorithms Benchmark Results Overall Top 20 Algorithms (by average time across sizes) Algorithm Skipped At Size Bogo Sort 12 Slowsort 333 Bead Sort 2500 Stooge Sort 5000 Smooth Sort 25000
Detailed Benchmark Results This benchmark report compares various sorting algorithms based on their performance across different array sizes. Each algorithm's performance is evaluated by its average and median runtimes, as well as the variance in its runtime measurements. A low variance (typically below 10%) indicates consistent performance, whereas a high variance (often above 50%) indicates that the algorithm's performance is less predictable. Algorithms that do not meet performance criteria at certain sizes are noted accordingly.
