	Insertion sort - Wikipedia, the free encyclopedia
		Insertion sort is a simple sorting algorithm, a comparison sort in which the sorted array (or list) is built one entry at a time.
		In abstract terms, each iteration of an insertion sort removes an element from the input data, inserting it at the correct position in the already sorted list, until no elements are left in the input.
		Each insertion overwrites a single value, but this is okay because it's the value we're inserting.

	Shell sort - Wikipedia, the free encyclopedia
		Shell sort is a sorting algorithm that requires asymptotically fewer than O(n²) comparisons and exchanges in the worst case.
		Insertion sort is inefficient, on average, because it moves values just one position at a time.
		When the gap is 1, the gap insertion sort is simply an ordinary insertion sort, guaranteeing that the final list is sorted.

	Insertion Sort
		Insertion sort maintains a sorted front section of the array [1..i-1].
		The way that elements of the array are `moved up' in insertion sort, a[j+1]:=a[j], involves just one assignment against three for an exchange in selection sort.
		If you are sorting non-numeric data, there might not be a convenient `-maximum value' to use as a sentinel and you will have to ensure that the inner loop terminates, in the case that `ai' is the least element in the data, by some other means.

	Insertion sort - Algorithmist
		Insertion sort is a simple sorting algorithm that is asymptotically equivalent to bubble sort, but is much faster in practice, because the number of swaps is at most linear.
		Insertion sort is preferable when the number of items is small - the constant is small enough that the benefit due to excellent locality and noticably better when the entire list fits in the lower levels of caching.
		Insertion sort in an array with gaps can achieve the theoretical lower bound of O(nlogn) of sorting with high probability.

	Insertion Sort (Site not responding. Last check: 2007-10-22)
		Although it has the same complexity, the insertion sort is a little over twice as efficient as the bubble sort.
		At the same time, the insertion sort is over twice as fast as the bubble sort and almost 40% faster than the selection sort.

	Insertion Sort
		Sorting algorithms were measured by a standard called big O. Big O measures algorithms by taking the worst-case that the algorithm could have and timing it.
		Insertion sort is also used in other sorting algorithms such as shell sort, merge sort and quick sort.
		Although both of these sorts are faster than insertion sort, insertion sort is the basis of these sorts and is therefore a good foundation to start teaching sorting.

	Insertion Sort
		There are improvements to the basic sorting algorithms to improve their Big O the ones that are improvements of insertion sort are shellsort, treesort, and merge sort; these sorting algorithms have been improved to achieve the best possible search Big O which is O(n log n).
		Insertion sort is one of the simpler sorting algorithms to program, understand, and teach.
		For example given the smaller sorted lists of (1,6,9,16,25) and (8,11,12,45,55) the end result for a merge sort of these two lists would be (1,6,8,9,11,12,16,25,45,55) to get the smaller lists ordered you can use insertion sort or which ever sorting algorithm you wish.

	AI Horizon: Insertion Sort
		Insertion Sort, like Selection Sort, is a fairly intuitive algorithm.
		Insertion Sort's advantages lie in that it works really well with almost sorted arrays.
		Still, for most cases, Insertion Sort is much faster than Selection Sort, and it is not very complicated to type, so it is used often in various computer science projects.

	Sorting Algorithms
		Some sorting algorithms are simple and intuitive, such as the bubble sort.
		Since the speed of a sort can vary greatly depending on what data set it sorts, accurate empirical results require several runs of the sort be made and the results averaged together.
		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.

	Insertion sort - CodeCodex
		Insertion sort is similar to bubble sort, but is more efficient as it reduces element comparisons somewhat with each pass.
		Although this algorithm is more efficient than the Bubble sort, it is still inefficient compared to many other sort algorithms since it, and bubble sort, move elements only one position at a time.
		However, insertion sort is a good choice for small lists (about 30 elements or fewer), and for nearly-sorted lists.

		Because sorting is so important and potentially so time-consuming, it has been the subject of extensive research in computer science, and some very sophisticated methods have been developed.
		The insertion sort, for example, is preferable to quicksort for small files and for almost-sorted files.
		In fact, an insertion sort is commonly used as a part of a quicksort implementation.

	Cprogramming.com - Algorithms - Insertion Sort and Selection Sort
		Selection sort is the most conceptually simple of all the sorting algorithms.
		Because a selection sort looks at progressively smaller parts of the array each time (as it knows to ignore the front of the array because it is already in order), a selection sort is slightly faster than bubble sort, and can be better than a modified bubble sort.
		Insertion sort does exactly what you would expect: it inserts each element of the array into its proper position, leaving progressively larger stretches of the array sorted.

	Shell Sort
		After sorting with a spacing of two, a final pass is made with a spacing of one.
		Typically the array is sorted with a large spacing, the spacing reduced, and the array sorted again.

	Insertion Sort
		Since multiple keys with the same value are placed in the sorted array in the same order that they appear in the input array, Insertion sort is stable.

		This means that they are sorted among themselves; each one is taller than the person to his or her left.
		On this pass through the sorted data, there may be no shifts, one shift, or two shifts, depending on where the third bar fits among the first two.
		If the data is almost sorted, insertion sort runs in almost O(N) time, which makes it a simple and efficient way to order a file that is only slightly out of order.

	Insertion sort
		The regular insertion sort is the most efficient of the 3 main naive approaches.
		Dichotomic insertion (also called binary search insertion sort) consists in using a dichotomic search to determine where to insert the new item, taking advantage of the fact the sub array is already sorted.
		This yield the most efficient algorithm in terms on number of comparisons, with a guaranteed bound of sum(log2 i) for i in [1..n-1], or log2 (n-1)!, which is strictly less than n log2 n.

	UnrealWiki: Insertion Sort
		Insertion Sort is an iterative sorting algorithm like Bubble Sort.
		If the removed input element is higher than the current result element, the element's correct location is found; remove it from its original location, insert it at the new location and start again from (2) with the next input element.
		For numeric arrays the last two steps can be optimized using BinarySearch to search the new location in the sorted part of the array if it's not already in the correct location.
