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

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

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

install-package GeneticSharp -Version 2.6.0

To install previous version that support .NET Framework 3.5:

install-package GeneticSharp -Version 1.2.0

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.

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

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);

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:

A Blazor client application template with GeneticSharp ready to run a Travelling Salesman Problem (TSP).

dotnet new GeneticSharpTspBlazorApp -n MyNamespace -o MyOutoputFolder

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

dotnet new GeneticSharpConsoleApp -n MyNamespace -o MyOutoputFolder
