GeneticSharp is a fast, extensible, multi-platform, and multithreading C# Genetic Algorithm library that simplifies the development of applications using Genetic Algorithms (GAs).

It can be used in any kind of .NET 6, .NET Standard, and .NET Framework apps, like ASP .NET MVC, ASP .NET Core, Blazor, Web Forms, UWP, Windows Forms, GTK#, Xamarin, MAUI and Unity3D games.

Setup

.NET 6

Only GeneticSharp:

install-package GeneticSharp

GeneticSharp and extensions (TSP, AutoConfig, Bitmap equality, Equality equation, Equation solver, Function builder, etc):

install-package GeneticSharp.Extensions

Unity3D

You should use the UnityNuGet to install GeneticSharp directly from NuGet.

Or you can use the latest GeneticSharp.unitypackage available on our release page.

.NET Standard 2.0 and .NET Framework 4.6.2

To install previous version that support .NET Standard 2.0 and .NET Framework 4.6.2:

install-package GeneticSharp -Version 2.6.0

Mono and .NET Framework 3.5

To install previous version that support .NET Framework 3.5:

install-package GeneticSharp -Version 1.2.0

Running samples

If you want to run the console, GTK# and Unity samples, just fork this repository and follow the instruction from our setup page wiki.

An easy way to run the Unity Samples, if you have a Android device, is download it from Google Play.

Usage

Creating your own fitness evaluation


public class MyProblemFitness : IFitness
{  
	public double Evaluate (IChromosome chromosome)
	{
		// Evaluate the fitness of chromosome.
	}
}

Creating your own chromosome


public class MyProblemChromosome : ChromosomeBase
{
	// Change the argument value passed to base constructor to change the length 
	// of your chromosome.
	public MyProblemChromosome() : base(10) 
	{
		CreateGenes();
	}

	public override Gene GenerateGene (int geneIndex)
	{
		// Generate a gene base on my problem chromosome representation.
	}

	public override IChromosome CreateNew ()
	{
		return new MyProblemChromosome();
	}
}

Running your GA

var selection = new EliteSelection();
var crossover = new OrderedCrossover();
var mutation = new ReverseSequenceMutation();
var fitness = new MyProblemFitness();
var chromosome = new MyProblemChromosome();
var population = new Population (50, 70, chromosome);

var ga = new GeneticAlgorithm(population, fitness, selection, crossover, mutation);
ga.Termination = new GenerationNumberTermination(100);

Console.WriteLine("GA running...");
ga.Start();

Console.WriteLine("Best solution found has {0} fitness.", ga.BestChromosome.Fitness);

Templates for dotnet new

If you're using .NET 6 or .NET Core, you can install GeneticSharp.Templates:

dotnet new -i GeneticSharp.Templates

There are 4 templates in GeneticSharp.Templates:

TSP Blazor application

dotnet new GeneticSharpTspBlazorApp -n MyNamespace -o MyOutoputFolder

Console application

A console application template with GeneticSharp, you just need to implement the chromosome and fitness function.

dotnet new GeneticSharpConsoleApp -n MyNamespace -o MyOutoputFolder
