####Build

####Code quality

####Release

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

Can be used in any kind of .NET apps, like ASP .NET MVC, Web Forms, Windows Forms, GTK# and Unity3D applications.

##Features

###Chromosomes Add your own chromosome representation implementing IChromosome interface or extending ChromosomeBase

###Fitness Add your own fitness evaluation, implementing IFitness interface.

###Populations

• Generation
• Generation strategy
  • Performance strategy
  • Tracking strategy

###Selections

• Elite (also know as Truncate or Truncation)
• Roulette Wheel
• Stochastic Universal Sampling
• Tournament
• Others selections can be added implementing ISelection interface or extending SelectionBase.

###Crossovers

• Cut and Splice
• Cycle (CX)
• One-Point (C1)
• Order-based (OX2)
• Ordered (OX1)
• Partially Mapped (PMX)
• Position-based (POS)
• Three parent
• Two-Point (C2)
• Uniform
• Others crossovers can be added implementing ICrossover interface or extending CrossoverBase.

###Mutations

• Reverse Sequence (RSM)
• Twors
• Uniform
• Others mutations can be added implementing IMutation interface or extending MutationBase.

###Reinsertions

• Elitist
• Fitness Based
• Pure
• Uniform
• Others reinsertions can be added implementing IReinsertion interface or extending ReinsertionBase.

###Terminations

• Generation number
• Time evolving
• Fitness stagnation
• Fitness threshold
• And e Or (allows combine others terminations)
• Others terminations can be added implementing ITermination interface or extending TerminationBase.

###Randomizations

• Basic randomization (using System.Random)
• Fast random
• If you need a special kind of randomization for your GA, just implement the IRandomization interface.

###Runner app (console) with samples

• AutoConfig

• Bitmap equality

• Equality equation

• Equation solver

• Function builder

  

• Ghostwriter

• TSP (Travelling toman Problem)

###Runner app (GTK#) with visual samples:

####TSP (Travelling Salesman Problem).

####Bitmap equality

###Multi-platform

• Mono support.
• Fully tested on Windows and MacOSX.

###Code quality

• 100% unit test code coverage.
• FxCop validated.
• Code duplicated verification.
• Good (and well used) design patterns.
• 100% code documentation.

Setup

PM> Install-Package GeneticSharp

Usage

Creating your own fitness evaluation

publicclassMyProblemFitness:IFitness{publicdoubleEvaluate(IChromosomechromosome){// Evaluate the fitness of chromosome.}}

Creating your own chromosome

publicclassMyProblemChromosome:ChromosomeBase{// Change the argument value passed to base construtor to change the length // of your chromosome.publicMyProblemChromosome():base(10){CreateGenes();}publicoverrideGeneGenerateGene(intgeneIndex){// Generate a gene base on my problem chromosome representation.}publicoverrideIChromosomeCreateNew(){returnnewMyProblemChromosome();}}

Running your GA

varselection=newEliteSelection();varcrossover=newOrderedCrossover();varmutation=newReverseSequenceMutation();varfitness=newMyProblemFitness();varchromosome=newMyProblemChromosome();varpopulation=newPopulation(50,70,chromosome);varga=newGeneticAlgorithm(population,fitness,selection,crossover,mutation);ga.Termination=newGenerationNumberTermination(100);Console.WriteLine("GA running...");ga.Start();Console.WriteLine("Best solution found has {0} fitness.",ga.BestChromosome.Fitness);
