Although somewhat slower in practice on most machines than agood implementation of quicksort, it has the advantage of a worst-case¿(n log n) runtime. Heapsort is an in-place algorithm, but is not astable sort.…

The only requirement is that the operator obeytwo of the properties of a total order: if a ¿ b and b ¿ c then a ¿ c(transitivity), for all a and b, either a ¿ b or b ¿ a (totalness ortrichotomy). It is possible that both a ¿ b and b ¿ a; in this caseeither may come first in the sorted list. In a stable sort, the inputorder determines the sorted order in this case. A metaphor for thinkingabout comparison sorts is that you have a set of unlabelled weights anda balance scale. The goal is to line up the weights in order by theirweight without any information except that obtained by placing twoweights on the scale and seeing which one is heavier (or if they weighthe same).…

It is much less efficient onlarge lists than more advanced algorithms such as quicksort, heapsortor merge sort. However, insertion sort provides several advantages:simple implementation, efficient for (quite) small data sets, adaptivei.e. efficient for data sets that are already substantially sorted: thetime complexity is O(n + d), where d is the number of inversions, moreefficient in practice than most other simple quadratic (i.e. O(n2))algorithms such as selection sort or bubble sort: the average runningtime is n2/4[citation needed], and the running time is linear in thebest case, stable, i.e. does not change the relative order of elementswith equal keys, in-place, i.e. only requires a constant amount O(1) ofadditional memory space, online, i.e. can sort a list as it receives it.Most humans when sorting-ordering a deck of cards, for example-use amethod that is similar to insertion sort.…

In most implementationsit is stable, meaning that it preserves the input order of equalelements in the sorted output. It is an example of the divide andconquer algorithmic paradigm. It was invented by John von Neumann in1945.…
