About

This repository is just an experimentation around genetic algorithms.

Most credits on this code goes to github user Murgio, whose code I refactored and optimized. See his Generic Algorithm Montage repository.

What does it do ?

Package fr.jblezoray.mygeneticalgo contains an implementation of a generic algorithm. Then, there are sample applications of the genetic algorithm in packages fr.jblezoray.mygeneticalgosample.*.

sample #1: Hello world

Generates an "hello world" :

sample #2: face mashup

Generates a face by combinating instances of itself.

input:

generation 1, 100, 500, 1000, and 2000:

I've tried to optimize the comparison of the generated image with the original one (the fitness evaluation). Here are a list of the algorithms I tried : samples/eval_fitness.pdf (in french !).

sample #3: Generates an images composed of disks

This sample generates an Generates an approximation of an image by composing arbitrary disks.

input:

output:

generation 200, 1000, 2000, 5000, and 10000:

How to run ?

Install a java jdk >=8 and maven >=3.0.5.

First, compile the project :

$ mvn package

Run sample #1 (helloworld) :

$ java -cp target/myGeneticAlgo-0.0.1-SNAPSHOT.jar fr.jblezoray.mygeneticalgosample.helloworld.Main

Run sample #2 (facemashup) :

$ mkdir statusDir
$ java -cp target/myGeneticAlgo-0.0.1-SNAPSHOT.jar fr.jblezoray.mygeneticalgosample.facemashup.Main samples/facemashup/match.png samples/facemashup/mask.png statusDir

The statusDir contains intermediate results.

Run sample #2 (disksimage) :

$ mkdir statusDir
$ java -cp target/myGeneticAlgo-0.0.1-SNAPSHOT.jar fr.jblezoray.mygeneticalgosample.disksimage.Main samples/disksimage/monalisa_croped.png statusDir

Have fun !
