What is the difference between insertion sort and selection sort?

Both bubble sort and selection sort are in-place sorts, which means they require no additional space to sort. Both are O(n).
Both also share worst/average case time complexities of O(n2). Selection sort also has O(n2) for a best case scenario, while an intelligent bubble sort implementation will have O(n) for a best case (already sorted) scenario.
Note that while looking at the numbers above seem to show that bubble sort has a slight edge over selection sort, in practice you should choose selection over bubble. It will very nearly always perform better in real-time tests.

Selection Sort
Insertion sort, sorts a set of records by inserting record into an existing sorted file. The closer the file is sorted the more efficient the insertion sort becomes.
A selection sort is one in which successive elements are selected in order and placed into their proper sorted positions.
In insertion sort we know the element and search for its place.
In selection sort we know the place and search the element to be placed.
It is a live sorting technique. It can sort the data as it arrives.
It requires all the data to be present at the beginning of the sort.
This is a stable sorting algorithm.
This is not a stable sorting algorithm.
If the initial data is sorted then -
Comparisons = n*(n-1)/2
Moves = 0
Comparisons = n*(n-1)/2
Moves = 0
If the initial data is in reverse order then -
Comparisons =(n-1)
Moves = 2+3+4+ ----- +n
Comparisons = n*(n-1)/2
Moves = n/2 * 3 (each swap consist of 3 moves)

Who invented insertion sort?
There are no records of when insertion sort was invented because people have been sorting things using the insertion sort and selection sort algorithms since before records began; they are ancient algorithms. You cannot be credited for creating an algorithm that already exists. Shell sort, which is a refinement of insertion sort, was developed much later, in 1959 by Donald Shell. His algorithm can be credited because it takes advantage of a computer's processing abilities, whereas insertion sort and selection sort rely purely on a human's processing abilities.
Different types of sorting techniques in c language?
types of sorting in c language are: insertion sort selection sort bubble sort merge sort two way merge sort heap sort quick sort
What is the difference between bubble sort and selection sort in pascal?
The traditional bubble sort moves any number of elements at most one position per iteration, while selection sort moves exactly one element per iteration. Both sorts require an exponential amount of time to produce their results.

How do you improve insertion sort algorithm?
If there was a way, it would be the new insertion sort! Theoretically you could reduce the time by using a linked list and searching to the position it needs to be inserted and inserting it. In practice however you would be better off simply using a different sort, especially if you don't want your data in a linked list. Selection sort is better when writing is expensive. Quicksort and Mergesort are faster on large data sets.

Who is best merge sort or insertion sort?
Merge sort is good for large data sets, while insertion sort is good for small data sets.
Why comparisons are less in merge sort than insertion sort?
the main reason is: Merge sort is non-adoptive while insertion sort is adoptive the main reason is: Merge sort is non-adoptive while insertion sort is adoptive

What are the applications of selection sort?
None. Selection sort can only be used on small sets of unsorted data and although it generally performs better than bubble sort, it is unstable and is less efficient than insert sort. This is primarily because insert sort only needs to scan as far back as required to perform an insertion whereas selection sort must scan the entire set to find the lowest value in the set. And although selection sort generally performs fewer writes than insert sort, it cannot perform fewer writes than cycle sort, which is important in applications where write speed greatly exceeds read speed.

What is the difference between sort of and kind of?
"Sort of" is used to indicate a small degree or extent, while "kind of" is used to suggest a category or type. For example, "I sort of like ice cream" implies a mild preference, whereas "I'm kind of hungry" suggests a general feeling of hunger.
