Witryna3 lut 2024 · This visualization shows how glidesort is adaptive to both pre-existing runs as well as many duplicates together: Note that both visualizations have different small sorting thresholds and auxiliary memory parameters to show the techniques in action on a smaller scale. Technique overview Comparison-based sorting algorithms have traditionally dealt with achieving an optimal bound of O(n log n) when dealing with time complexity. Adaptive sort takes advantage of the existing order of the input to try to achieve better times, so that the time taken by the algorithm to sort is a smoothly growing function of the size of the sequence and the disorder in the sequence. In other words, the more presorted the input is, the faster it should be sorted. def of rehabilitation
