When implemented well, it can be about two or three times faster than its main competitors, merge sort and heapsort.
22.
An ordinary merge sort using four working files organizes them as a pair of input files and a pair of output files.
23.
In this case, ordinary merge sort factor is 2.0, while polyphase overall factor is ~ 2.73.
24.
Other examples of adaptive sorting algorithms are adaptive heap sort, adaptive merge sort, patience sort, smoothsort, splaysort and Timsort.
25.
:( ec ) Bucket sort and merge sort seem to be two general sorting algorithms that are reasonably suitable for human implementation.
26.
However, it must then repeat the process for the remaining A and B subarrays for the current level of the merge sort.
27.
Similarly, the merge sort algorithm sorts an unsorted list by dividing the list into halves and sorting these first before merging the results.
28.
The polyphase merge sort fixes this discrepancy by padding the actual distribution with imaginary " dummy runs " to simulate an ideal run distribution.
29.
This table roughly corresponds to the reduction factor per dataset moved tables shown in fig 3 and fig 4 of polyphase merge sort . pdf
30.
"' Block sort "', or block merge sort, is a sorting algorithm combining at least two stable sorting.
