When level of glucose falls to zero, bitozoon dies. At the beginning there is a preset number of bitozoa on your screen. At this moment surviving bitozoa are allowed to have some sex and they are mixing their genes producing the offspring. Neurons of every new bitozoon are a mix of its parents neurons. Some neurons weights are mutated.
New generation starts to explore the screen eating fodder.
It s as interesting as a life itself. This process can be described as a creation of genetic algorithm - every bitozoon is an algorithm, and their genes are neurons. I can write a short paper about bitozoa and their evolution, but I leave it to you - after some hours of twiddling with the simulation you should be able to do the same thing. Please take into account that program starts always the same simulation - blind bitozoa. If you want to see something other you must press Ctrl-P to access parameters windows.
