    Tournament Selection Genetic Algorithm

    A basic class for running tournament selection based genetic algorithms in JavaScript.

    A simple example...

    This will produce a random population of 50 genotypes, each made up of 0's or 1's, evolving for 1000 generations to contain as many 1's as possible (see fitness function).

    const GeneticAlgorithm = require('GeneticAlgorithm');
    
    // Length of each genotype
    const geneLength = 8;
    
    // Genes available for producing genotypes
    const genes = [0,1];
    
    // Count of genotypes
    const populationCount = 50;
    
    // Count of times (roughly) each genotype is evolved
    const generationCount = 1000;
    
    // Class instance
    const geneticAlgorithm = new GeneticAlgorithm(geneLength,genes);
    
    // Very basic fitness function
    geneticAlgorithm.fitness = G => G.reduce((a,v) => a+v,0);
    
    // Generate and evolve a population
    geneticAlgorithm.run(populationCount,generationCount);
    
    // Log the newly evolved population
    console.log(geneticAlgorithm.population);
