Jenetics.Net

Jenetics.Net is a port of the popular Java Genetic Algorithm framework Jenetics to .NET Core.

Documentation

Currently the documentation is not ported, but because of the nearly identical structure, look into the Jenetics (javadoc) and the user manual (pdf).

Requirements

Build time

• .Net Core 2.0: The .Net Core 2.0 SDK must be installed.

Build Jenetics.Net

Check out the master branch from Github.

$ git clone https://github.com/rmeindl/jenetics.net.git <builddir>

Jenetics.Net is currently not using anything thing else for building besides .Net Core projects.

Go to src/core/Jenetics for building the library

$ dotnet build

Go to src/core/Jenetics.Tests for running the xUnit Tests

$ dotnet xunit

All artifacts can be found in bin\Debug\netcoreapp2.0.

Go to src/examples/<example> for running on of the examples, e.g. src/examples/HelloWorld

$ dotnet run

If you want to publish an example including the .Net Core runtime as self-contained application, define the runtime

$ dotnet publish -r linux-x64 --self-contained

or

$ dotnet publish -r win-x64 --self-contained

All artifacts can be found in bin\Debug\netcoreapp2.0\linux-x64\publish or bin\Debug\netcoreapp2.0\win-x64\publish.

Example

Hello World (Ones counting)

The minimum evolution Engine setup needs a genotype factory, Factory<Genotype<TGene>>, and a fitness Function. The Genotype implements the Factory interface and can therefore be used as prototype for creating the initial Population and for creating new random Genotypes.

using System;
using System.Linq;
using Jenetics.Engine;

namespace Jenetics.Example
{
    public static class HelloWorld
    {
        // 2.) Definition of the fitness function.
        private static int Eval(Genotype<BitGene> gt)
        {
            return gt.GetChromosome().As<BitChromosome>().BitCount();
        }

        public static void Main()
        {
            // 1.) Define the genotype (factory) suitable
            //     for the problem.
            Genotype<BitGene> F()
            {
                return Genotype.Of(BitChromosome.Of(10, 0.5));
            }

            // 3.) Create the execution environment.
            var engine = Engine.Engine.Builder(Eval, F).Build();

            // 4.) Start the execution (evolution) and
            //     collect the result.
            var result = engine.Stream().Take(100).ToBestGenotype();

            Console.WriteLine("Hello World:\n" + result);
        }
    }
}
