The oscillating merge sort " was designed for tapes that can be read backward and is more efficient generally than either the cascade merges ."
32.
This process repeats for each level of the outer bottom-up merge sort, at which point the array will have been stably sorted.
33.
In many practical cases, long natural runs are present, and for that reason natural merge sort is exploited as the key component of Timsort.
34.
A better result can be obtained by using a parallelized merge algorithm, which gives parallelism, meaning that this type of parallel merge sort runs in
35.
Consequently, the polyphase merge sort needs to be clever about the initial distribution of the input data's runs to the initial output files.
36.
A natural merge sort is similar to a bottom up merge sort except that any naturally occurring runs ( sorted sequences ) in the input are exploited.
37.
A natural merge sort is similar to a bottom up merge sort except that any naturally occurring runs ( sorted sequences ) in the input are exploited.
38.
Merge sort was one of the first sorting algorithms where optimal speed up was achieved, with Richard Cole using a clever subsampling algorithm to ensure merge.
39.
Merge sort itself is the standard routine in Perl, among others, and has been used in Java at least since 2000 in JDK1.3.
40.
In the " worst " case, merge sort does about 39 % fewer comparisons than quicksort does in the " average " case.
