![]() Gridworld's simulations are highly customizable. You can do more than just simply observing though. When you come back to check after a day or two, you will find a thriving eco system of virtual creatures. You can simply start a simulation and take your hands of completely. The cool thing about evolution is that it is an autonomous process that requires no guiding hand. Through this process of natural selection, creatures become increasingly well adapted to their environment within each generation. This causes the best adapted genes to increase in numbers while the weaker genes are decreasing in numbers and are eventually rooted out. Natural selection causes those creatures with the best adapted genes to have more offspring. When a piece of dna is copied when creatures reproduce, there is a small chance of mutation in the dna. In turn, the brain decides how the creature behaves during its life. in Gridworld, the dna describes the morphology of the neural network (brain) of the creature. Just like in nature,Ĭreatures have DNA, a digital code that describes the morphology of the creatures. They can be recognized as colored blocks moving around the grid. Evolution can therefore be observed in hours or days instead of thousands of years.Ĭreatures in Gridworld are a simple and abstract versions of biological life. ![]() Conditions in this two-dimensional ecosystem are right for evolution to occur through natural selection.Ĭreatures live short and replicate fast. Gridworld is an artificial life / evolution simulator in which abstract virtual creatures compete for food and struggle for survival.
