	comb sort
		Note: Bubble sort can be seen as a variant of comb sort where the gap is always 1.
		Comb sort does a single "bubbling" pass (ala bubble sort) over each set for each gap or increment, whereas Shell sort completely sorts each set.
		Dave Ring wrote a variant (Java) that switches to an insertion sort when the gap is less than 9.

	COMB SORT : Encyclopedia Entry
		In computer science, comb sort is a relatively simplistic sorting algorithm designed by Stephen Lacey and Richard Box, who described it in Byte Magazine in April 1991.
		At this point, comb sort continues using a gap of 1 until the list is fully sorted.
		The final stage of the sort is thus equivalent to a bubble sort, but by this time most turtles have been dealt with, so a bubble sort will be efficient.

	Shell Sort Algorithm
		Sorting algorithms are important in computer science because of the need to organize data into ascending or descending order according to each data records key.
		Sorting by selection is where the largest or smallest number in a set is put at the end or beginning.
		Sorting by distribution is where all items are compared to each other and a position index is given to each one based on how many are smaller or larger than it is. Radix sort is a sorting by distribution method.

	Sorting algorithm Summary
		Efficient sorting is important to optimizing the use of other algorithms (such as search and merge algorithms) that require sorted lists to work correctly; it is also often useful for canonicalizing data and for producing human-readable output.
		Sorting algorithms are prevalent in introductory computer science classes, where the abundance of algorithms for the problem provides a gentle introduction to a variety of core algorithm concepts, such as big O notation, divide-and-conquer algorithms, data structures, randomized algorithms, best, worst and average case analysis, time-space tradeoffs, and lower bounds.
		For sorting very large sets of data that vastly exceed system memory, even the index may need to be sorted using an algorithm or combination of algorithms designed to perform reasonably with virtual memory, i.e.

	[ hacked by deviance ] - Introduction to Sorting Algorithms
		Sorting is a topic every student of computer science who plans to graduate from university successfully will have to deal with.
		The task of a sorting algorithm is to transform the original unsorted sequence to the sorted sequence.
		Its main principle: The unsorted sequence is sorted by means of exchanging in such a way that to the left of a certain element only values lower than it remain, and so that to the right of a the same element only values greater than it remain.

	Shell Sort
		The shell sort is a "diminishing increment sort", better known as a "comb sort" to the unwashed programming masses.
		The size of the set to be sorted gets larger with each pass through the list, until the set consists of the entire list.
		A sample C program that demonstrates the use of the shell sort may be downloaded here.

	Shell Sort
		Box and Lacey claim that their comb sort achieved the best balance of the two between short times and predictability, as it sorts random lists and previously sorted lists with about the same efficiency.
		One of the nicest features of a Shell sort is that it is not subject to extreme worst case situations.
		Even using the shell sort, users are going to be twiddling their thumbs if you try to sort much more than 10,000 data items.

	sort
		Formal Definition: The sort operation may be defined in terms of an initial array, S, of N items and a final array, S′, as follows.
		quicksort, heapsort, Shell sort, comb sort, radix sort, bucket sort, insertion sort, selection sort, merge sort, counting sort, histogram sort, strand sort, J sort, shuffle sort, American flag sort, gnome sort, bubble sort, bidirectional bubble sort, treesort (1), adaptive heap sort, multikey Quicksort, topological sort.
		The term "sort" came to be used in Computer Science because the earliest automated ordering procedures used punched card machines, which classified cards by their holes, to implement radix sort.

	Wyo Java Lecture Notes
		This sorting algorithm is similar to the bubble sort but instead of comparing and swapping adjacent elements, elements that are a certain distance away from each other are compared and swapped.
		The Shell sort is much faster than other incremental sorts since very large and very small key values are quickly moved to the appropriate end of the list.
		One requirement for a radix sort is that the data elements must be able to broken down into parts and the range of those values has limits.

	Sorting Algorithms
		Their simple modification of bubble sort which they call `combsort' eliminates turtles quickly by allowing the distance between compared items to be greater than one.
		The above implementations of bubble sort, heapsort, quicksort, and combsort were tested on from 200 to 1600 items, each consisting of a 9-character key and 11 characters of data.
		After the tables had been sorted, they were sorted again to measure the time for sorting already sorted data.

	Sorting (Was: BogoSort)
		WIth middle of 3, thats a very rare case, given only by unlucky random numbers (and then usually fixed in the next call to sort the 1st subarray- 1 or 2 of the numbers used to find the pivot are changed).
		Insertion, selection, or comb sort are better than bubble, and just as easy to write.
		So doing a counting sort over an array with a large variance in numbers is bad (and it wont work on floats).

	Comb Sort/Merge by Mike Morrow
		It reads in the entire file, sorts it in stages, in memory, then merges the sorted groups to the output dataset.
		Quicksort has some very high penalties (nearly sorted files for one) and is best when not run to completion but handed over to another type of sort to finish up the busywork such as bubble sort.
		However, the sort fields must add up to the total length of the record or data will be lost.

		Sorting is a rich lode of learning available to all programmers.
		If the number of swaps made in each call to the bidirectional bubble sort were counted, and used to determine future values of GNDR, we would expect it to be called "adaptive." Changing the title from "An NlogN Adaptive Group Sort* Algorithm" to "An NlogN Comb* Sort Algorithm" would help considerably.
		There is little doubt that a carefully optimized Comb Sort will soon be published [that is] demonstrably better than Quicksort for a wide range of input data types, simpler to write, and not using recursion.

	SORTS
		We'll be looking at 2 general classes of sorting algorithms in terms of their run time execution efficiency:
		O(f(n)) as applied to the run time of an algorithm states that, up to some constant factor, the function f(n) gives an upper bound on how the algorithm is performing for large n; saying, as n gets larger, the growth in execution time will be no worse than that shown by f(n).
		Insertion Sort tries to overcome this by scanning only enough entries to determine where to insert the new one.

		Can someone explain to me how shell sort works and tell me why it can not be used on linked lists.
		The shell sort is by far the fastest of the N2 class of sorting algorithms.
		The shell sort is still significantly slower than the merge, heap, and quick sorts, but its relatively simple algorithm makes it a good choice for sorting lists of less than 5000 items unless speed is hyper-critical.
