Insertion Sort
Insertion sort belongs to the O(n2) sorting algorithms. Unlike many sorting algorithms with quadratic complexity, it is actually applied in practice for sorting small arrays of data. For instance, it is used to improve quicksort routine. Some sources notice, that people use same algorithm ordering items, for example, hand of cards. Algorithm

Insertion sort algorithm somewhat resembles selection sort. Array is imaginary divided into two parts - sorted one and unsorted one. At the beginning, sorted part contains first element of the array and unsorted one contains the rest. At every step, algorithm takes first element in the unsorted part and inserts it to the right place of the sorted one. When unsorted part becomes empty, algorithm stops. Sketchy, insertion sort algorithm step looks like this: [pic]

The idea of the sketch was originaly posted here.
Let us see an example of insertion sort routine to make the idea of algorithm clearer. Example. Sort {7, -5, 2, 16, 4} using insertion sort.

The ideas of insertion
The main operation of the algorithm is insertion. The task is to insert a value into the sorted part of the array. Let us see the variants of how we can do it. "Sifting down" using swaps
The simplest way to insert next element into the sorted part is to sift it down, until it occupies correct position. Initially the element stays right after the sorted part. At each step algorithm compares the element with one before it and, if they stay in reversed order, swap them. Let us see an illustration. [pic]

This approach writes sifted element to temporary position many times. Next implementation eliminates those unnecessary writes. Shifting instead of swapping
We can modify previous algorithm, so it will write sifted element only to the final correct position. Let us see an illustration. [pic]
It is the most commonly used modification of the insertion sort. Using binary search
It is reasonable to use binary search...

Shaker Sort
(implemented by Jason Harrison)
Shaker Sort is like Selection Sort in that it passes over the unsorted part of the array to select the next element(s) to add to the sorted part. It differs in that with each pass it looks for the smallest and...

Experiment Name:Insertion sort Algorithm
Objective:To learn about Insertionsort algorithm,know how it works and use it in real life.
Application: Suppose there exists a function called Insert designed to insert a value into a sorted sequence at the beginning of an array. It operates by beginning at the end of the sequence and shifting each element one place to the right until a suitable position is found for the new element. The function has the...

...Discussion: Coded by a polymorphic gene, Alu insertion is found within an intron of the tissue plasminogen activator (tPA), which is lacking in ancient DNA sequences (Batzer et al, 1994). In this experiment, the lining of cheek cells of 105 individuals were tested for the presence/absence of Alu insertion titled tPA-25 by using PCR amplification. Using oligonucleotide primers to border around a tPA-25 insertion site, PCR products were amplified for...

...Analysis of Amplification of Alu insertion polymorphism by PCR
Introduction
Alu elements have been accumulated in human genome throught mankind evolution, reaching over 1 million copies in genome. They are short, and repetitive DNA fragments found in primates. Each Alu element is known to have 300 base pairs in length. DNA repeats contribute to partial gene deletion or duplications in many cases of hereditary diseases.Alu insertion polymorphisms consists of...
