     This is a typical example of how evolution works. A population of (customizable) Creatures try to Evolve according to some tasks. A Creature is composed by springs, "muscles" and a neural network. There are "intelligent" and "dumb" springs. First ones change their rest length according to the neural network outputs. The other simply react to external forces to mantain their invariable rest lengths. From V6 there are "muscles". Muscle is an angle constrain between two links. The NN outputs determinate even the Angle that they must have. The Creature's Neural Network Inputs are: Vx,Vy & "Pressure" of touching ground Points, Creature Rotation (DX and DY), Height from ground, X Y Velocities and Rotational Velocity. The Creature's Neural Network Outputs are: "Intelligent" springs rest lengths and Muscles rest angles. EVOLUTION (genetic algorithm): At Each generation there are 3 sons wich parents are "randomly" choosen from the best previous generation creatures. (Some sons mutate their genes with low probability (M)). Then sons are Evaluated. (This 3 sons replace the previous generation worst creatures)

Note: Due to the size or complexity of this submission, the author has submitted it as a .zip file to shorten your download time. Afterdownloading it, you will need a program like Winzip to decompress it.Virus note:All files are scanned once-a-day by Planet Source Code for viruses, but new viruses come out every day, so no prevention program can catch 100% of them. For your own safety, please:
  1. Re-scan downloaded files using your personal virus checker before using it.
  2. NEVER, EVER run compiled files (.exe's, .ocx's, .dll's etc.)--only run source code.
  3. Scan the source code with Minnow's Project Scanner

If you don't have a virus scanner, you can get one at many places on the net
