What is BitNeat ?

A lightweight and beginner friendly implementation of the neat algorithm

Usage

//Create a manager with all necessary properties
//The Evaluate function has to a function that returns the fitness of 
//the current network. The BaseGenome, Mutator can be created outside 
//the obj initializer and be customized to your needs.
var manager = new Manager
{
  EvaluationFunction = Evaluate,
  BaseGenome = Genome.Generate(1, 1, true),
  Mutator = new Mutator(),
};

//Setup ManagerOnOnLifecycleFinishedEvent 
//This event is called a lifecycle is finished
manager.LifecycleFinishedEvent += OnLifecycleFinishedEvent;

//This method evolves the network untill the given fitness is reached
//and returns the network that has reached the given fittnes
var network = manager.TrainUntil(0.98);

//After the process is finished you can use the network.
//The network can also be saved and restored using the 
//toString and fromString method.
while (true)
{
  Console.Write("Input: ");
  var input = Convert.ToDouble(Console.ReadLine());

  //Calculate and print out the result
  Console.WriteLine("Output: " + String.Join(", ", network.Calculate(new[] { input })) + "\n");
}

How it works

The network is evolved by a slightly modified version of the NEAT algorithm.
