  Shellsort
Shellsort is one of the oldest sorting algorithms, named after its inventor D.L. Shell (1959) [Sh].
Shellsort can be implemented as a sorting network if the data-dependent Insertion Sort is replaced with Bubble Sort.
Shellsort was originally published by D.L. Shell [Sh].

 fejj's log: shell sort   (Site not responding. Last check: 2007-11-04)
With this new table of increments, I was able to achieve an average sort time of about 0.09 seconds.
In fact, ShellSort() in combination with the above increment table will sort an array of 2 million items in about the same amount of time as our optimised BinaryInsertionSort() took to sort 100 thousand items.
Note: As requested, I have exported all of my sorting articles into a single sorting.pdf document and have placed it on my website at http://primates.ximian.com/~fejj/doc/sorting.pdf and will keep this file updated as I write new articles on sorting algorithms.

Insertion sort is the same as the shellsort code without the outer loop and with the value of gap set to 1 in the inner loops.
Perform unit testing to verify correctness of your version of shellsort using Hibbard's gap increments.
A suggestion is to prompt the user to enter a choice for one version or the other and then have your test run the one chosen (using an if statement) rather than rewriting the main method code for two different versions of the test driver.

 Shell sort
Shellsort is a simple extension of insertion sort which gains speed by allowing exchanges of elements that are far apart.
The idea is to rearrange the array to give it the property that every h

These conditions would be also be true when using the "sort" command in the shell.
I have also implemented a quicksort, a shellsort, an insertionsort, and a mergesort in AppleScript.
They are not too hard to do if you know the sorting algorithm.

Hi, I'm having troubles with this one, I’m using an algorithm very similar, but I’m getting W.A. I I’m thinking that there are a tricky test case.
I don't think that their are any special cases...

Task 3: Implement Sedgewick sort using the sequence of increments proposed by Sedgewick:
You will need first to implement a function that computes the elements in the sequence and stores them in an array increments[], and then organize the outer loop in the shellsort function to take the gaps from that array.
Include code to count the number of copying operations (called not quite correctly swaps)
