Genetics-node NPM

Genetics-node

0.2.8

Introduction

Genetics-node is a node.js framework which implements Evolutionary Algorithm. Genetics-node is written in C++. The framework is in early phase and has a lot of work.

Motivation

Evolutionary Algorithms (EA) gives us the possibility to know the input of a certain system by using the system and defining output.

explain

Simple example: if we have y = 2 ⋅ x. Then our system is 2 ⋅ x, our function is y. If we define the output y (e.g. y = 2) then we can solve for x.

Installation

npm install genetics-node

Code Example

const genetics = require('genetics-node');

let result = genetics.evolution(
    1000,               // population size
    "Hello World",      // string goal
    0.1,                // mutation rate
    true,               // print every evolution
    0.2,                // ratio between crossover and mutation
    50                  // amount of elites
);

console.log(result);

The evolution function takes:

population-size
string as goal
mutation-rate between 0 and 1
ratio between crossover versus mutation
the number of elites
print each evolution or not. Set true or false

Example

Hello World test command:

node test
