But to understand what that means, we need to understand what stability is in this context. The Sunrise sort is a sorting algorithm with a rather unique property: it is fully unstable. Introsort (introspective sort): quicksort as a default, switching to heapsort when recursion is too deep or insertion sort when the collection size is below a certain threshold (it is the one currently used by.Trimsort: a combination of insertion sort and merge sort (specifically designed for python).Dual pivot quicksort: a combination of insertion sort and quick sort ( source).And they both use hybrid variants (such as the Trimsort and the Dual Pivot Quick Sort) which rely on different techniques.īelow, a few tables showing which sorting algorithms have been historically used by modern frameworks and languages: Collection types Both C# and Java, for instance, change which sorting algorithm to use based on the size of the collection. ❓ Which sorting algorithms are used by modern frameworks?īecause each sorting algorithm has its own pros and cons, most modern languages and frameworks are relying on “mixed” solutions. Other ones may find useful applications in contexts which lack the flexibility of random access memory, or which can make use of highly parallelised architectures.

Quick sort, merge sort and-to some lesser extent- insertion sort, have been the most influential ones in modern software engineering. Besides being taught in academia as a necessary step towards the few ones which are actually used, of course! And while each one does it in a slightly different way (perhaps even under slightly different constraints), most of them find no application in modern computer science. One that is only bound to get bigger, given that there are potentially infinitely many different strategies to sort the elements of a list. It is also worth noticing that an entire “zoo” of sorting algorithms exists. Yet, many have developed an unhealthy obsession for them, which is probably only comparable to the obsession and respect that mathematicians hold for prime numbers. So fundamental that the French word for “computer” is “ ordinateur“, which actually means “sorter”. It is not unsurprising that sorting algorithms play a fundamental role in Computer Science. One advantage of the Big O notation is that does not necessarily have to be the exact function, but it indicate to “order of magnitude”.
More specifically, to talk about how long an algorithm takes, as a function of its input size. This is a Mathematical notation adopted by Computer Scientists to talk about the efficiency of an algorithm. In this section we have used the so-called Big O notation (also known as the Bachmann–Landau notation).
