AIrium

This project aims to build an interactive simple artificial life simulation that uses genetic algorithm and fitness evaluation to improve, over different generations, the performance of the agents.

For now, agents are evaluated based on how much they eat. Using default settings you can see them evolve to be herbivores, but by tweaking it is possible to get carnivores or scavengers.

In the GIF you can see an environment similar to the default, but smaller. Most creatures are pretty efficient herbivores with a few showing slight carnivore behavior. This was obtained in only 5 generations of training, in about two minutes on an average CPU.

Since version 0.5 it is possible to save your best creatures to disk so you can reintroduce them to different environments later and avoid losing very efficient agents.

Features

• Artifical Life creatures with simple brains
• Artificial selection to ensure the evolution of the creatures over time
• Many configurable settings to create different environments (still a little limited, but I'm working on it)
• Easy to use with working default settings for beginners, highy configurable and fully open source for hackers!
• Save and Load your configuration and your creatures
• Every creature has a unique, persistent name generated using its brain topology, so on every computer the same creature will have the same name
• Multithread design, resizeable window, configurable simulation speed, multiplatform support, free and open source!

Download

Visis the releases page to download the latest version. It was tested on Linux, OSX and Windows using the latest version of Java 8. On OSX there is a small bug in the GUI but you can fix it by resizing it to be bigger.

Planned features

• More behavioral variety
• More sensors for the creatures
• Ability to save and load simulation states
• More in the issues page

Controls

• The Configuration page in the GUI will let you tweak many parameters and pause the simulation
• You can drag with the mouse to move the camera and zoom with the mouse wheel

Development

To work on the project or try it out, install Netbeans and follow Libgdx's guide to set it up for Libgdx development (mobile platform are ignored for now so you won't need the Android SDK). It should be possible to work on the project without using Netbeans. You can find further explanation in Libgdx's wiki.
