Use joints, bones and muscles to build creatures that are only limited by your imagination. Watch how the combination of a neural network and a genetic algorithm can enable your creatures to "learn" and improve at their given tasks all on their own. IMPORTANT: This is a simulator and not a game. If you are not interested in the concepts of natural selection, genetic algorithms and neural networks and watching them work together then this is probably not the app you're looking for. Everyone else, please continue reading. The tasks include running, jumping and climbing. Can you build the ultimate creature that is good at all of the tasks? I want to stress again that there are no real objectives. Even if a creature of yours reaches 100% fitness, you don't win anything except for (hopefully) lots of excitement and joy. IMPORTANT (again) : The simulation is pretty CPU heavy so it will crash on most old and/or low-powered devices. If your device does not meet these minimum performance requirements you should NOT download this app. If you just experience some lag you might be able to improve the fps by lowering the population size in the start menu. For more information on how the algorithm works behind the scenes and everything else you might be interested in click on the "? " button in the creature building scene. 1.1 Update: You can now save and load your simulation progress. There is also a Mac & PC version available for download and a browser version for you to try out on the main project website (keiwan. itch. io/evolution).
