A package that simulates a Genetic Evolutionary Algorithm among its generations.

Installation

Add genetic_evolution as a dependency in your pubspec.yaml file.

dependencies:
  genetic_evolution: ^0.1.0

Import Genetic Evolution:

import 'package:genetic_evolution/genetic_evolution.dart';

Basic Usage

First, you must define your own GeneService, describing the Genes within a DNA strand. Notice that we are defining a Gene to be of type <String>.

class MyGeneService extends GeneService<String> {
...
}

Then, you must define your own FitnessService, describing how well an Entity's DNA performs.

class MyFitnessService extends FitnessService<String> {
    ...
}

Next, you can initialize a GeneticEvolution object.

GeneticEvolution geneticEvolution = GeneticEvolution(
      geneticEvolutionConfig: GeneticEvolutionConfig(
        numGenes: 10,
        mutationRate: 0.25
      ),
      fitnessService: MyFitnessService(),
      geneService: MyGeneService(),
    );

And finally, you can get the next generation using nextGeneration().

Generation generation = await geneticEvolution.nextGeneration();
