Algorithms.NET

Open source library containing the most used sorting and searching algorithms.

In this library you can find the most used sorting & searching algorithms and that are must know for developers, and their implementation, these algorithms are as follows:

Sorting:

• Bubble Sort
• Insertion Sort
• Selection Sort
• Bucket Sort
• Merge Sort
• Quick Sort
• Counting Sort

Searching:

• Binary Search
• Ternary Search
• Jump Search
• Linear Search
• Exponential Search

You can play with these algorithms in Algorithms.NET.Debug

To view and compare performance of each algorithm, manipulate the code inside :

SearchingBenchmark.cs & SortingBenchmark.cs

To run the benchmarks, comment out :

var searchingBenchmarkSummary = BenchmarkRunner.Run<SearchingBenchmark>();
or
var sortingBenchmarkSummary = BenchmarkRunner.Run<SortingBenchmark>();

Then run the project in Release Mode

Sorting algorithms comparison:

Note : BuiltIn Sorting algorithm uses an unstable version of QuickSort, and after .NET 4.5 it now uses Insertion sort for n<16, otherwise it starts with Quicksort and switches to Heapsort when the number of partitions (recursion depth?) exceeds 2 * Log^N. Called: Introsort, and that explains why it is the fastest.
